catalytic converter

I just recently took the upper intake and injectors off and put them back on. I had a bit of a fuel line problem and fixed that. But now when I turn it on it smells sweet or something. While driving it there is this smell that reminds me of eggs or something cooking. I got home and heard a...

Hi all. I'm looking for some help. I have a 2013 Explorer XLT with a 3.5L and 185k miles. I just got an all new exhaust from the cats back installed by a local shop. I'm now getting a slew of codes. The shop said to drive it and see if they clear. Cleared the codes and took it out for two hours...

I have a '17 PIU w/ the 3.7 NA. When I got the car, it had codes for bad cats, bad O2 sensors, and an evap leak. So far, I've replaced the purge valve which fixed the evap leak, both downstream O2 sensors which fixed nothing, and both cats. When I did the cats, it turns out I accidentally bought...

I bought a used 2004 Ford Explorer XLT The outside temp that shows is always over 100 degrees, even now in the fall, no matter how warm or cold it is outside. How do I fix it? Would also like to know where the catalytic converter is located, I may need a replacement.

99 Eddie Bauer 4.0 SOHC with almost 220xxx miles. It starts up, runs for awhile, but then dies and doesn't want to start back up. Normally if I let it sit for awhile it will fire back up. It is NOT throwing a check engine light. I have been hearing a rattle from underneath at idle, I thought it...

Local mechanic pulled off one of my heat shields and tossed it; said it was loose anyway/rattling. Said 'not to worry'. Ford seems to have a different idea. I haven't been able yet to crawl under and see which one(s) are missing. There are generic pieces of heat shield(-ing) available at low...

Have a 91 Explorer 4.0 Eddie Bauer and I need a new catalytic converter. When i look underneath I see the section of the exhaust which has two oem converters. My question is to replace the cataloytic converter section im planning on buying the universals made by magnaflow or flowmaster, do i...

Been away from the forum awhile. In that time I traded in my 98 Sport for a new 2013 Limited with the 3.5L Ti-VCT V6. My 2013 now has about 141k miles on it. About 4 months ago I got the P0420 code. In the last month it has been joined by the P0430 code. No other codes have surfaced nor any...

2002 Explorer 4.6, if read tons of stuff about exhaust for them but I haven' found a real answer on something. If you were to remove the cats, replace them with straight pipe then installing the o2 sensor in the same relative spot would the system work with no CEL? And with that being said...

I drive a lot and the last month or so I have been getting a faint oil smell in the cab. I have looked over the car extensively and not found any leakage. I do not smell oil in the exhaust and the oil level is unchanged. my mechanic and I looked over it together and he removed a vacuum hose to...

It starts up and runs like a champ. But after about 3-5 mins of it running. It starts running really rough and will eventually shut off all on its own. It smells really bad because of it running so rich. Ive already cleaned the snot out of the MAF sensor, knocked out both catalytic converters...

Hey Guys! my name is Courtney and I just purchased my first Ford, a 2002 Explorer XLS 276XXX. I was unfortunately scammed when I bought this vehicle and now we are trying to get the parts and price things to fix it and get it together by next week. So if anyone can help that would be awesome...

I know there have been threads on this before but I was wondering in terms of longevity, what is the best aftermarket catalytic converter? I noticed that Magnaflow have both a “high metal” and an “OEM” grade catalytic convertor but both have the standard 25,000 mile internal / 50,000 mile...

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...

Hey all, over the weekend my explorer decided it wanted to top out at 5mph, and since despite being 12 years old, it's definitely the nicest bed newest car I own, so I felt I should go to a shop instead of kicking it until it works like I've done with my other cars. It's got 115K on it, and full...

I drive a 2004 Ford Explorer 4.0 Sohc 6 cylinder 4wd, 64,000 miles. A few weeks ago I noticed a loud rattle when starting the engine and on the Down Rev. I eventually traced the noise to inside the passenger side catalytic converter. The last few weeks I've been trying to figure out why my...

Let me start by saying this is an awesome forum and has helped me resolve numerous issues to date. With that said I need some advice. I have a 98 explorer 4.0 SOHC which recently developed a p0430 code and a CEL. I have also experienced a decrease in gas mileage from about 16 to now about 11mpg...

I have a 2006 4.6L Explorer. My check engine light came on. I purchased a OBD reader and found that the code was a P0420. I reset the code. I read in the owners manual to see how to get the vehicle emissions ready for emissions testing. I ran the engine through the profile but the OBD still...

So I've been having some serious problems lately, especially once I get up past 35mph. My specific issues are as follows: Firstly, it's not throwing a CEL at me at all. Somewhat rough idle, RPMs aren't jumping around or anything, but it starts and sits (in Park) at around 600 and then...

I have a 2003 Ford Explorer XLT (V8-4.6L) in storage at my fathers. He drives it occasionally. The next time I am home, in about less than a month, I need to change out the catalytic converters. Dealer quoted $1700, but we have access to a lift, so we can do it ourselves. However, the assemblies...

Hey everybody, I just found this cool site while looking for info on cats for a 1999 Exp XLT. The Dealer says it needs new cat(s) and it'll cost about $2ooo. A quick web search shows prices from $56 up to $500+. I should mention that this will be for a California Explorer. (Thank you for...

Here goes, hope someone can help I'm in a bad situation my mechanic is telling me one thing, and my mechanic cousin is telling me another. We can't seem to diagnose the problem. 2004 Ford Explorer, 137k highway miles kept in great shape regular maintenance. For the past year it has been making...

I am trying to remove the old catalytic Converter from ford Explorer 2006. I have the bolts, nuts, and oxygen sensors remove. It is a Y configuration. How do I remove it and put the new in.

Hey all, I was driving in a field in the dark last night, and managed to drive my front tires off a ledge and bottomed out on a rather tall rock. After being pulled out, the car is running quite rough and loud, and i can see that i completely crushed the exhaust where it goes into the...

My cat(s) are clogged. The shop called me and told me the cat on the left (drivers) side is blown out and emptied into the back cat, the passenger side one was not as bad. They are drilling out the bolts that support the tranny. They told me they have the new catalytic converter installed but...

i bought my truckabout a year ago. recently i noticed a "patch" on my cat. im guessing that the insides are gone. my trucks semi loud. will that cause low mpg? also would a bad o2 cause 11 mpg? when my maf is connected i get black sooty smoke and the truck sounds like its under water, mpg goes...

So i was puttin a new muffler on my 97 explorer sport and i saw that i have 2 cats. Anybody know if this was standard for my explorer and if i can legally take at least one off to try and get a louder sound. i live in NC and im pretty sure the law is you just have to have one cat, never really...

Hi everyone, First, Thanks to everyone on this forum. I haven't found so much helpful information anywhere else on the net. Well, as mentioned in a previous post, this is the next issue I'm facing with my XLT. The rear catalytic converter has separated from the exhaust pipe, and now...

Okay so i have a huge problem. I have a 96' 4.0 that didn't pass smog because the cats are bad. (threw a P0420 code). Apparently, all of the aftermarket cats that an hour long internet search seemed to find, are NOT Cali legal. I called Midas (longshot) asking if they could do it. After...

I need to know if my 96 limited has one or two cats. My car has the check light on and when i run the code it says that my emissions are not to operating standards. I think that means that my cat is bad, however the car still passes CA smog! So, I am asking how many Catalytic Converters does my...
