I bought a 94 f150 4.9/E40d a couple weeks ago. The truck only has 89k miles and is really clean and original. It's had a bit of a high idle since I got it, but otherwise rand great. Unplugging the iac did not affect the idle at all. I tested the iac, tps, checked for vacuum leakes and everything checked out good. Now when you press the gas pedal the truck wants to immediately stall out. I pulled the computer tonight to have a look inside and found this. Could this cause the problems I am having? I'm guessing either way the computer needs to be replaced. Thanks for any advice.

 

Bingo! We have a winner! One freshly fried computer.

 

Yeappers, same problem here with my '92, 300, 5spd. $274 later for remaned PCM, good to go!

 

I would also say "Kentucky fried".

 

Awwww, that'll buff right out!!!! Well, somebody had to say it!!!








Just kidding, actually it looks cooked like several that have been pictured around here lately...

 

Leaky capacitors are pretty common and not that hard to change out.

Well actually that may not be far from the truth, leaking electrolytic capacitors are a known problem with these PCM modules(or any electronics that is 20+ yrs old) but unless they completely short out and burn up the board then it's entirely possible the module can be salvaged by simply replacing all those little oil can looking things. If you are at all handy with an electronics soldering iron or know somebody that is then it won't take more than a few minutes to replace the capacitors , just make sure they are the same uF or mfd value, the same or greater voltage rating, and are installed with correct polarity... look for a + marking on the board under the cap or take pictures and put everything back the same way.

 

+1 for fixing that.

WAY cheaper than replacing the EEC with a "reman"... which may or may not actually be reman'd.

 

Thats a bit pricey if all they do is swap out the caps and retest. I'm handy with a soldering iron, maybe I should start a caps replacement service.

 

True, and I was outraged with Ford and their dozen or so different PCMs. Mine was destroyed! The caps leaked out and ate through the traces on the board. I wish I could record what I really had to say when I started looking for the replacement. I'd you do a search at O'Reilly auto parts, there are a lot of different PCMs..and since I didn't have ime to trial and error, I ponied the money so I would know I had an identical PCM. My PCM was coded, T2D1. There were cheaper ones, but I can't gamble on a vehicle if its not running. I also tried replacing the caps and jumpering the breaks in the traces, but the fuel pump ran continously.

 

I ordered a cardone reman today at autozone. It was $200 and will be in by 6pm today. Going to install it tomorrow. Ill report back as to wether or not it fixes my problem.

 

Do not be surprised if that Cardone "remanufactured" PCM is DOA. Cardone is notorious for repackaging PCMs with new stickers and no testing whatsoever. Good luck...

 

We will see. What other choices are there? It seems that there are only a couple companies that reman them.

 

Standard Motor Products (SMP) is my favorite: Standard - eCatalog

These two places could repair yours and come recommended from other FTE members:

Auto Computer Exchange | Remanufactured OEM Auto Computers
Ecu Repair Now, automotive circuit board testing and repair

 

You'd been better off repairing yourself or having yours repaired local first, odds are pretty good it work fine again once those caps where replaced.

Don't wanna take it on yourself any local TV repair shop or any place does board level electronic repair work should be able to handle the job and for around 20 bucks or so.

About a 15 minute job change those caps for a guy does that kinda work every day and should be able to tell you by looking at the board what its chances are once the caps are replaced. Damaged and beyond repair, or real good chance it will be just fine was caught it in time.
