Help please! My 90 accord is stalling. I have replaced ICM, ECU, cap rotor and wires. Plugs are 5k miles old... It will start, run for 10 to 15 minutes.. when its warm, somewhere in that range it will shut off, and the CEL will come on. When I bridge the service wires, there is NO code yet the CEL just stays lit. What should I try next please?
