Losing power sometimes. NOT DME relay
Hey all. I am baffled. I figured my dme relay was bad, replaced it and didn't help. Got worse today 20 min after I replaced it. I was driving in the last week a few times and lost power for 20 sec, and car would still idle but giving it gas did not help, then it would just fix itself. It is a 90' c2 cab. Today, it cut out getting on the Mass pike. same deal, this time at high rms, and would idle, but die if I gave it gas. Tried restrting it and same thing about 4 times. I finally held the pedal down to floor and fired it up and instantly reved it right up and it was fine for whole 200 mile round trip. I went to replace the coils and ignitor things a few months ago, and it would not run on just one of the new coils, so I gave up and put back in the old black coils, and threw the new bosch brazilian coils on the shelf. I am leaning towards the coils finally giving up. could it be a dying fuel pump? I even swapped mass air flow flapper a month ago and i dont think that was it. like I said it has been getting worse in the last week, but was fine today after 200 miles. Even hit 110 mph a couple times without really noticing. Any ideas? I need to stop throwing dollars at problems and do more thinking..
Thanks.
Thanks.

i had a similar problem and it was the solder joints on the DME board.
my solution to fix:
- remove DME and open
- take circuit boards to local TV repair guy
- ask him to check solder joints
- paid $20 and all was perfect
just a suggestion anyway!? good luck.
do you have a friend where you can try another DME?

Dme cracks scare me. How much of a bitch is it to remove? do I have to remove the seat? and how much for a new dme or repair the old?
Rob, you mentioned earlier you can read codes? Maybe I should take you up on your offer and swing over and get some codes!
Thanks.
