lt1 please help.....
I just put a new msd opti and water pump on my 1994 lt1. When I start up it will idle normal for about 45 seconds and then the rpms will fluctuate between 1,500 and 2,000 rpm and seems to miss some. Posting to see if anyone has any advice and thanks in advance.

Sorry man, it's your opti. Welcome to my hell. Went round and round with msd because my opti caused the same exact thing. Ditched the msd and got a Delco and never had another problem
