Hi guys, i have a 1996 caravan. recently my service engine soon came up, i ran a scan any pulled code P0352. am experiencing rough idling. i have changed the spark plugs, coil pack and coil wires, still no improvement. I noticed the service soon light usually come up when am low on gas and disappers when i add gas. please i need help on how to solve this problem. my engine is a 2.4l

 

Only component left is the PCM. You can test the PCM coil drivers by connecting a test light at the coil connector to pins 1 to ground then 3 to ground. The light should consistently blink as the engine cranks. If the light doesn't blink verify wire continuity from there to the PCM. If good then replace the PCM.

Coil ...................PCM
pin 1.................. Connector E44 pin 3 (dark blue/tan wire)
pin 3.................. Connector E44 pin 11 (gray wire)
