82 Check Engine light came on again...
Previously had some ECM problems, and replaced it.
Car has been running fine, and on Saturday, the check engine light came
on, car ran rough and spotty, and finally went into "LIMP HOME" mode and
revved at about 2200 rpm all the way. Got the car home, turned it off,
re-started it 10 minutes later, went out for a quick ride, and no problem,
no check engine light. :confused:
Anyone experience similar problem on their 82 Crossfire??

i had a similiar problem. It ended up being the shop that did my work had not done a proper restoration of the module. All it took was remove module clean and "striaghten" connections, and it recovered.

No not the distributor module. Actually on my it was the chip on computer behind the glove box. The car wasnt running right and after it came back from the shop it was worst. It wasn't a corvette shop and the idiot did not know what he was doing. They said they hadn't done any thing, but i found several of the pins on the chip spread. I re-aligned them and reinstalled the chip, did a learn lap and everything was OK. After, that I copied, shrank, and laminated the codes and keep it in my wallet with a paper clip. I realized after that I would only bring it a vette shop if I couldn't do it myself.
In a nutshell, sometimes careless craftmanship. Was the first shop a corvette shop?

Yes, it was a Corvette shop.
We replaced the ECM, the chip on the ECM and the distributor module.
It ran pretty well for a while, and all of a sudden, it started acting up again.

I would try unplugging, cleaning connections, and reconnecting. If you have new modules it could be a loose connector. Do you know which codes are presently in your memory?

Pull the code, then you'll know roughly where to look. If there's no code but the normal 12 it could be the 12 is not set bu the normal way (ign. on, engine off -> no crank signal) but there might actually be a problem there.
