I just recently did a full tune up (oil change, new plugs, and air filter). It has 140k on it and she drives it like shes 80 lol. Super easy on it. Didnt even think to look- does it have an in-line fuel filter? Or is it in tank? thanks for the response

update: replaced the PCM and it made no difference but did give me a few codes the last one wouldnt. It was showing the cats were clogged. Replaced all three of them and the thing is PERFECT now, including the tranny. Only problem left is mileage. Still getting only 13.3? Any other ideas?

wow thats a lot of info lol. Ill def sit down and research thank you

Yes, starts and drves normal as of right now (other than normal tranny probs as stated). This is the first time it has done this and is proving to be intermittent. I had a buddy drive it around to get it to operating temps and he said he had no problems other than a slight miss. I have a DPFE...

I have the correct part number so will definitly stick with that one. Thank you. What do you mean by pats?

Something else to consider. She said the CEL was flashing at her if that helps any. Also, I have been having troubles with her tranny. At normal/easy driving around town its perfect, but as soon as you lean into it to drop into a passing gear it just winds out and WILL NOT shift until you...

ok ill look into that some more. Its my scanner but im out of state and had somebody else do it for me so I may have misunderstood. Thanks

that is one of 2 codes that pointed me towards a bad coil IIRC

It's my scanner, so what tells you its busted?

good site. Thanks for the help. Thats about the best i have found so far.

well I tried the local auto stores and nobody can get it.... any other suggestions?

That would be awesome. I just assumed they wouldnt be able to get something like that. I'll check it out, thanks!

codes were: -p0307 -p0316 -p0352d -p0405 -p0420 -p0430 p0455 Thank you

Girlfriend's 03 limited 4.6 started loping and died. Codes are pointing to PCM failure. Ford wants $600. To find one used how specific do I have to be? Does it have to be out of another limited? Or can it be any model? Can it be out of a 4.0 and just reflashed for the 4.6? Etc. You see what I'm...

lol Thats really all its there for right?

I just assume slipping because it is completely gutless when downshifting. Motor screams she just doesnt move. i have driven another one identical to this and it hauls ass

sorry, it has 140,000. should I go ahead and get the tranny flushed? I have a good snap-on scanner and im not pulling any tranny codes on it.

lol ya I messed with it a few times at first. But it hasnt been reset since, and typically the meter is high so who knows how bad it actually is until i get home. It would suck to go back to motocraft plugs. Those E3 werent cheap lol. Does this thing have an in-line fuel filter? Or did they...

did you figure this out bud? Mines doing the same thing....

OK this is going to be kind of a long post so try to bear with me. 2003 limited explorer w/4.6. Bought it for $4k with a cracked exhaust manifold. Before I replaced it the lie-o-meter was showing 13.7 MPG. After replacement of manifold, EGR and tube, oil change, E3 plugs and new air filter the...

awesome. I posted another thread about the door jam/ajar light too, just havnt gotten to it yet. I didnt think they would be related. you guys really know your stuff. Thanks!

2003 (build date 12/02) limited 4x4 explorer. The alarm is going off randomly. No clue there. Also, the entry button pad on the door is not working. I was told the code is under the interior panel by the passenger side rear seat. Tried that, and nothing. I dont think its working at all though...

thanks for all of the info guys. That sucks this is such a common problem.

This is the only place I could figure to post electrical, so feel free to move need be. I just bought a 2003 limited explorer with the 4.6. My dash lights were super dim so obviously I went to turn them up and the overhead cab light comes on and will not shut off until I start driving down the...
