PROM questions and now EGR question '90 C4
I put an ad in the parts section, but maybe I should just ask.
I recently bought a 1990 corvette with 26k on the clock. I noticed when I bought it, that it idled a bit rough in gear (automatic tranny), but if I put it in neutral it was much smoother at a stop. Driving was fine...just the idle problem in gear.
I called the dealership where I bought it from and told them about it. They said bring it back for the mechanic to look at it. The first repair shop took a look and said one of the plug wires was bad, so it was swapped out. Since the wire was no good, the cylinder had not been firing properly and the plug was fouled up. So the mechanic cleaned up the plug and sent me on the way. During my drive back to the house, the car sputtered and died.
I got the car towed to another repair facility that the dealership wanted. The new mechanic eventually changes all the plug, the computer, and fuel pump with a bill of around $600. So I go pick it up and after about 25 miles, the car sputters. I hit the gas...no throttle response, and it stalls. I could start the car up, it would idle but if I revved it, the RPMS would go up and back down leading to a stall out. I tried this a couple times and then the car would not run at all. So another tow back to the mechanic.
Well I called today to check the most recent attempt at fixing it. The mechanic now says that the PROM is bad and he is attempting to find one off a 1990 Automatic somewhere.
The question is, do I need to find a 1990 Corvette used PROM (which seems hard to do) or is their an alternative? Is there a place that sells blank PROMS and can program for a 1990 Corvette? I haven't seen any sites selling used PROMS, only piggybacks that I need to plug the stock PROM into.
I am lost at this point. Can someone help?
