egr

Hi all new member here. First things first. I've used the search function and have read all applicable threads before posting. I have a 2010 XLT with a never ending emissions problem. Started with P0401, P0403, P0443, P0455 and finally P0457. I have spent many hours researching, diagnosing...

Hey guys, I have a 1997 f150 with a 4.6l v8, recently I took the throttle body and off to clean the EGR ports that were clogged from carbon buildup, unfortunately when I tried to take off the EGR both bolts holding it in place broke off, now I need to go to a machine shop to get the broken...

So I had a check engine light come on on my 2021 explorer xlt checked the ford pass app and scanned it with my tool, and both said EGR high temp. I looked under the hood and found a massive nest of grass on top of the engine, mind you this is a daily driver. where would I find the EGR valve to...

So my intake manifold was rotted, leaked, and basically died on the road. Got a buddy to tow it, we got the manifold replacement, and fixed it quickly in 6 hours. Found the egr tube was snapped du to rotting, so we Jerry rigged it for now, however I need to fix it or delete it. That's one issue...

2000 explorer xlt, a/c 5.0 litre. what are these hoses and cylinder parts called, and can they be serviced by anyone other than Ford? the loing hose starts at the intake manifold and connects to a valve under LF wheelhouse, The same valve has a second hose which connects to a metal tube in...

Hello everyone. I have a 2007 Ford Explorer Eddie Bauer edition. I bought this used 3 years ago and have had nothing but trouble. First I had to replace the engine, then have the transmission rebuilt. Yesterday I took it in to have the EGR valve replaced and they called me an hour later stating...

Hi all, I just completed a engine replacement on my 02 Ford Explorer XLT 4.0. Runs and drives great when cold, but once it warms up a couple different codes pop up. When they appear, the engine stumbles when idling to the point that it kills itself. Occasionally, it will hesitate and stumble...

2000 Explorer XLT 2WD 4.0L SOHC JOB1 5-Speed Automatic 5R55E. Can someone confirm the following? Thanks. The EGR system uses a EGR Pressure Sensor... not a EGR Temperature Sensor, right?

Hey guys! I was hoping that some would know off the top of their head or if they happened to have the bolts that mount the intake tube to the EGR valve. It's a 98 4.0 OHV. When I purchased my vehicle it had incorrect sizes and is currently leaking. To clarify this is the tube that enters the...

Good afternoon, Sorry about so many edits but I keep getting new info. See the end. My first post here but I've checked the forum out for many useful items over the years. 2005-4.0 SOHC with 150K but it's been well cared for as I've had it for 10+ years. It usually runs great with 22 mpg but...

i have an exhaust leak at the manifold, im getting 10-11mpg with regular driving and im getting 3 codes for the EGR, o2 sensor and maf sensor. could my exhaust leak be causing all of this? would cutting off exhaust(after o2 sensors) at least temporarily fix my issues?

Hello again, So, I'm back with another question. Could a broken, open, EGR tube cause my Misfire issues? I assume that the answer is yes, however I have seen many, and I mean many, different answers about the subject in my search, and figure the Explorer Forum should be my final...

Hey yall... so I have a 2008 Mercury Mountaineer with 180k miles on it. She runs GREAT! But this "Check fuel inlet" message that keeps showing up on my dash board every time it rains, is driving me insane. Does anyone know how to make it stop? Ive tried cleaning it out and all but it still does...

Hello everyone i am a new member. I have an 06 4.0 explorer that i have been having an error code p0401. I replaced the egr, replaced the intake manifold gaskets, and opened a propane tank around the intake and hoses to search for a vacuum leak to no avail. What else could i check to help my...

Hi my name is Joel, I am a new member of this forum and just purchase a used 1996 Explorer 5.0 AWD. It has low miles for the year, 105,000, and is in extreamly good condition. My problem with the Explorer is when I start it it has a slight ticking noise that goes away when the car warms up, but...

My 99 explorer 5.0 has CEL P0102 low voltage MAF sensor. I have replaced the sensor, the connector, throttle body sensor, IAC valve, gaskets and checked for vacumm leak although there seems to be a leak i can't find after the MAF sensor. What else can be causing this code? I can't get it smogged...

I have been getting the lean codes for Bank 1 and Bank 2. I clean and replaced MAF. I had previously replaced the famous vacuum elbow (and it's still good). I have had a smoke test done to find any other vacuum leaks. A small amount of smoke came from the EGR, replaced it. The codes have...

So was working on my Explorer last weekend, wanting to change out the EGR Valve, as it is froze and rusted. Well I was trying to get the one nut off, and I ended up breaking the EGR Tube off clean at the nut down at the exhaust. So I ordered a new EGR tube, and am ready to put on the new EGR...

Hello, NEED HELP! enquiring about a temporary solution for the holiday season, Parts are difficult to find here in New Zealand! I have had my 05 v6 XLT Explorer diagnosed, misfire piston 1 and a number of error codes, replaced the plugs, (looked like the originals!) then narrowed it down to the...

Hey guys a few weeks back my 1998 4.0 OHV Explorer started misfiring bad, not keeping an acceptable idle, and burning tons of unused fuel. It was on my way home from work. Finally the CEL came on as I was parking it. The code brought up was p0402 as I'm sure you know it was excessive EGR flow...

Hello everyone I have a 98 SOHC V6 in the UK and it is running very rough on cold start ups. I've replaced the PCV valve and the idle air control valve which did make a difference, albeit for the engine to rev quite high every time it's started hot or cold. Is there any suggestions on what I...

Hey there! First off, let me start by saying that I am so proud of where ExplorerForum has come! The website looks great, and the community is bigger, better, and more active than ever! Let's begin... For a long time now, I have had an oil leak. I would put 2 quarts of 5W-30 in, and about 3...

Had some problems with a P401 "EGR Flow" message on my 96 Explorer not clearing and decided to try the old Italian Tune Up to see if that would fix it. So today, I was driving the two hours to the bee yard and once I was off of the interstate and out of traffic started to cycle through a series...

Hello to all knowledgeable folks here at explorerforum.com. I have a question concerning my 96 ranger 4.0l . I recently put in a new used motor,after the install the engine fired up no problem compression was good on all cylinders,the motor seems to me lacks in power as I remember I like the 4.0...

Hi I changed my egr valve today and the one I picked up from Autozone has a hole that I never seen before on the side of it? The new one makes the truck run worse because of the hole... It just pushs air out like an exhaust leak. Any thoughts or anyone know why that hole is there?

My mountaineer has a low emissions sticker on it an I live where emissions is not a big deal. I was wondering if I can delete my egr on the truck if I can were can I find the parts to do so. Any input would be great. Also my volts drop on the gauge so I had it tested an they said battery is...

I bought a used 94 Explorer about 6 weeks ago from a "not so honest" person. My fault totally for letting my guard down. Anyways, I ran the codes with a jumper wire & I took care of a few of them but I got 335 EGR -Feedback signal is/was out of range - EVR or PFE, 332 EGR - did not open/respond...

I had my exhaust manifold gasket replaced to fix an exhaust leak on Tuesday. It was supposed to be a simple job, or so the mechanic said, don't in 3 hours, no problem he said. It took all day Tuesday and most of Wednesday. When I got my truck back, he said everything was fine. I drove to...

Hi everyone. New to the forum. Have a check engine light ans PO401 error code. Removed and tested the EGR valve (sucked on it to see if it would activate & say engaged). Pulled the throttle body, did not see any apparent blockage. There is a tube that leads from the EGR valve mount that turns 90...

I have looked at the DeeZee running boards and the EGR integrated ones. I am really leaning toward the EGR ones but the drilling required is really turning me off. Anyone have these installed? How do you like them? Photos? Here is a link to the ones I am looking at...

Recently my Explorer has started sounding like it's got a turbo on it when it's under load. She usually only does it under heavy acceleration or going up hills. The driving characteristics haven't changed, but I just wanna know what could be causing that spooling sound? Could it be related to my...

My '03 Ford Explorer v6 has been shuddering a lot for the past year. It will rev up and down when idle, even stall out occasionally. It has gotten progressively worse so I took it in to a mechanic. They told me to change the Mass Air Flow Sensor and spark plugs. I did so and it worked great...

I have a 1996 Ford Explorer with a code of p401. We replaced the EGR valve and the DPFE. I am still getting a p401. I erase the code and darned if it does not come back. I want to check for a vacuum leak but I have no idea were the hoses are or where to start. Any other ideas of what to...

Alright, Hi again guys. I'm still having EGR issues and it's just now getting bad enough for me to be nervous driving far from home. The entire EGR system is new, replaced the EGR, EVR, and PFE. They all have vacuum, and function correctly when manually tested. However, most of the time...

Okay, I posted a thread a while back on a rough idling problem. Thought I had it fixed, but apparently the car thinks otherwise. I keep pulling codes every few times I do something to it and the codes have gone from a consistent 332 to a consistent 335. These codes will not quit, they keep...

My check engine light came on. I checked the codes. It showed an EGR system code, not exactly sure which one off the top of my head. I replaced the EGR valve and DPFE. Reset the computer, and it still popped up. SO i replaced the EGR vacuum solenoid. Cleared the codes again. Still comes...

Hey all. I've been chasing vac leaks. I have rough idle, flares, fades, stumbles in OD at low rpm. I tested the diaphragm by adding vac and it opens and closes properly. There are tiny holes on the underside of the disk rim. One in the back seems to pull air. Is this a leak, failure of...

I have a 98 Explorer 4.0 OHV that has been giving headaches for a couple of months. During cold start, the engine idles rough almost like it's missing until I get the engine to 2500 RPM then it smoothes out. Anyway, a couple of month ago, one of the lines to the DPFE had a slice in it so I...

(this is over a period of about 6-8 months) To keep a long story short, my 93exp started running like crap and went from 20+ mpg to 14. just changed the plugs and wires 2 months prior. I thought it was a plugged cat so I cut the bottoms out of them and took the stuff out, then welded the...

My 2000 4.0 OHV has a leak in the EGR Valve Tube, it has been welded once, so repair is probably not a good option. I had a garage look at it, they are recommending replacing the LH Manifold, the tube, the EGR Valve, because everything is so fused together. One manifold stud is broken, they fear...
