91 ZR-1 Cutting Out Under Load - ZR-1 Net Registry Forums

GregCrowe · 02-22-2009

Gave Jeff's ECM a try, and as the norm with this car.......... not fixed. At this point it pretty much has to be coils. I see both Summit and Jeggs have their own high performance, low resistance coils for $31-33 each. I think I'll give the Summit coils a shot, not too expensive and they're red which will match the car and plug wires. If that doesn't fix it, I'm totally stumped.
