hello fellow f-body people. I am a new member though i have viewed this forum off and on for years. I now need to see if anybody has advise. I have a 93 Z28 auto and just recently it has developed a high rpm problem. as it reaches the 5000 or so rpm mark it has a strong miss and occasional pop from exhaust. have noticed a flame with the pop. feels to be ignition to me. i know of the common opti-spark problems and replaced it wee over 50k miles ago. my thought is that it may be going out again. only problem i have seeing that is that they normally just go completley out. if anybody has seen this problem and has an idea please let me know.
thanks, Larry
