Where do these cars pick up a tach signal from. I think that's my problem. I was guessing the Ignition Control Module from reading other posts on some old threads. I now know that that's not the problem and still have the same issues. It seems to be intermittent. Runs badly more than good right now. This all started last week. Started it up for work and when I came out to leave, It was idling rough and wouldn't rev up. I drove my wife's car. She drove mine a few hours later and didn't have a bit of problem. It did it again last week on friday and only straightens up once in a while now and the tack seems to follow suite. When its running right the tach works good and when it's running rough, the tach isn't working properly. Just need some experienced advice.
