Re: 94 cutlass suprem 3100 keeps losing spark
This could be a pcm issue, try tapping the pcm when this occurs see what happens, also look for corroded conections at the pcm.

Re: 94 cutlass suprem 3100 keeps losing spark
I trade taping the pcm and check all wire conters. The will run for minets some time days befor losing spark when it loses spark the icm never loses power to it. It cranks over for a while before it starts
