my 93 lt1 motor is giving me problems starting when it gets warm, i have a ignition module going in sunday the 1st when it comes in. but not sure looking at timing, vacume, the worst opti spark and this one has like 4 years on it maybe 15000 miles, hoping thats not the prob. been tuning alot with new setups but then this started last oct 2 days before i put it up with a ripped up rearend. what may cause this. some eratic idle but cant really find a leak. im lost right now been dealing with it for a week.
