I have a '94 Z28 with a stock LT1. It runs like a reped ape and makes shetlin ponies out of mustangs but I'm afraid it's gonna bite me soon. In normal driving conditions, if I let off the gas and then get back into it (1/4 throttle or so) it will chug for a minute. If I lace into the pedal, it'll smoke the tires and take off like a shot again and be fine. I tried to get any fault codes from the ECM but there's something stopping the ECM from giving me codes. A friend buts alot of x-police cars with the LT1 in them and says he's needed to replace the entire Opti-spark assembly for $600 (part only, no labor!!) on 4 of them at about 100,000 miles. I have 92,000 miles and a limited bank account. Does anyone have any opinions on this or had this problem? Please help!!!!

try starting out light first,

give it a normal tune up, replace the plug wires while your at it. (there a pain in the *** near the front on the module) a fresh fuel filter wouldnt hurt either. see how it goes from there. always start small, no sense throwing parts at it that cost big Buck when it could be somthing simple as a idle sensor or somthing
