rough idle

Stopped at a gas station and afterwards check engine light came on. Throwing code p219a and p0303. Rough idle and drinking some gas. Have had the coils and plugs and injectors checked and cleaned. Everything is running right. Changed the purge valve, still not fixed. Clear the codes and start...

When it's below below freezing outside my explorer has trouble starting and initial rough idle. When I scan for trouble codes I get P0302 which is a misfire on cylinder 2 and a P0316 which is engine misfire detected on startup. Once it's been running for about 30 seconds to a minute the rough...

Okay, so this is a simple question, since my explorer is a 98 the plastic is obviously kinda old. However, the vents are hard to mess with because the close/open knobs like to stick, and moving it up/down and left/right is also hard, cause the plastic just wants to stick together so I feel like...

Hello all. I've just completed a valve cover gasket replacement on my 2002 4.0L SOHC 4WD Explorer, with help from several threads on here. I've gotten everything back together (after hours of messing with the EGR tube), and now I've got a rough idle and a hissing sound from the rear of the...

2003 Mountaineer 4.6. I've posted a few items about assorted issues on this truck in the last month. The truck was running fine, but I recently changed my intake manifold because it was cracked and slightly leaking coolant into cyl. 5 spark plug well. I was a PITA, but I got it done and fired it...

Good morning, Over the last month 1/2 I have been dealing with the "rough engine/shake at idle" issue that many others on here have posted about. I bought this 2005 Explorer from my aunt after my uncle passed last October. It has 118,000 on it now. I want to layout what I have all done thus...

My 2002 explorer has a terrible rough idle and clanking sound. After its running a minute or 2 the RPM's level out just under 1000 but the clanking sound is still there. I'm getting lean codes p0171 and p0174 as well as misfire codes in all 6 cylinders. I've checked for vacuum leaks with carb...

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...

I need help desperately I have a 97' Explorer Sport (that I love very much) but i cuts out whenever it is put in reverse or sometimes (very rarely) at a red light with my foot on the brake. I got a check engine light once. took it to auto zone and got a code for an air leak. took it to a...

Hello, I have a 2001 Mercury Mountaineer AWD 5.0. When low idle such as backing out of garage or taking off from a stop light I get a rough engine sometimes not always. Less than a year ago I had a mechanic work on it for the same reasons and problem went away. He replaced spark plug wires one...

So i just jumped back into the Explorer game, replacing my old 5.0 with a SOHC 4.0 and after a week am having some issues with cold starts, seemingly random misfires, and a CEL I can't check yet. From the little i know of this engine I'm suspect of intake gasket failures. It runs rough and...

Aloha team, 3 quick questions: 1. Anyone have tips for determining if the PCV hose from the back of the engine is bad? How about replacing it- any easy way to remove/replace? 2. I just replaced intake gaskets - how can I tell if I'm still leaking? 3. Where else to look for a persistent 171...

Hi. Ok, I have several questions re my "new" aquisition of a 93 explorer, 4wd, 6 cyl. Friends told me if I could get their old explorer running, I could have it. Had been sitting in yard 5 years. Original owners. Only needed battery, and tire and viola! Off and running. 89,000 mi, 1 owner...

So I bought this 2000 ford explorer about a year ago and have been happy with it for the most part. However as of late I was noticing that the power seemed to have dropped a little bit which I attributed to age. But now a few other symptoms have appeared. When I'm driving down the road the car...

When we start it up in the mornings it idles rough and constantly stalls until we can get it running. After which the RPM starts bouncing between low and high. When we slow down to a stop it gets really rough and threatens to stall until we give it gas. Our issue is similar to the one in this...

I bought my 1998 ford explorer xlt v6 sohc about a month ago now. I replaced the belt and will be doing a tune up this weekend but I believe that it has a vacuum hose leak. I heard hissing under the good after I turned the engine off. It was a soft hiss on the left side(when you face the front...

I have a 1991 Ford Explorer that will run fine until you turn the car off. If the car is at operating temperature and you let it sit for 20 minutes or so the car will not start. If you get there after about 15 minutes it will start, but you have to hold the accelerator to the floor because it...

I own a 93 Mazda Navajo, 4x4 (explore) and it keeps running a little rough when giving her enough gas to keep speed. The check engine light will come on when this happens then go off. I know I need a new muffler asap there is a huge hole in it. Well its not even a hole the whole bottom of the...
