Subject: Corvette 1992 Misfire by ecorti95 on 2009/8/23 13:04:26
Corvette 1992, 48 K miles, bought it new, the problem is that it started misfiring intermittently 1 year ago, and stalls occasionally, it seems to run well for the first 15 minutes, but it gets worse after engine warms up. I pulled codes: Module 1: C41, H41, H74 Module 4: H36, H16 Module 9: H62, H72 It will run well for a time, but then it will start misfiring and stalling again. It has always re-started without problems after stalling.
Can anyone tell me if this is the optispark gone bad?
