My 1.8 Ljet left me stranded yesterday. I did the usual debug stuff. Turns out the ECU is overfueling the engine. Injector pulsewidths are 10ms to 15ms under cranking conditions. This is roughly 10x what I would expect at startup. Anybody have any suggestions for what might be causing this problem? The airflow sensor maybe?
Thanks for any suggestions you can offer. -dave sprinkle |

Check your grounds FIRST....!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
BROWN wires. LOOK in your manual for ALL the injector connection points. Then just for shits and grins. Pinch off your cold start injector fuel line with a flat faced locking pliers (Vice Grip). Or pull the fuel line and plug it. Just to keep that possibility out of the over fueling equation. Clayton |
