94 LT1 check engine light after opti change
my upper rad hose by pass hose leaked coolant all over and in my opti. so I just put a new one on. followed the FSM. the car started right up and ran smooth. but the SEL came on for about a 2 mins then went off. all the mean time the engine ran fine. was that the ECM retimming the engine with the new opti.
