The car starts but will not idle, loses power and shuts off. I changed all the ignition coils, cam sensor, both crankshaft sensors, and the condenser and nothing has changed. Replaced the fuel pump initially because the car had been setting up for two or three years. I did all the check list on one of your pages and discovered that testing continuity from terminal 1 on the ECM using a Simson Analog Meter on lowest setting and I read only half dial on all wires to the coils.

I think the ECM needed to learn the Idle speed, it is running fine now, thank you very much.
