Sometimes you can fix it by DISCONNECT the negative terminal on the battery, THEN remove and reinstall the connectors to the ECM and add some dielectric grease to the contacts. Sometimes one or two of the pins can be loose or have the wires get frayed.

The VCIM is the OnStar/Bluetooth module. That lives behind the rear quarter panel cover, passenger side (I think). The same fix is described.

We tried this fix just now. I will check back in tomorrow after I really drive it. The engine light is out which is a good sign, but I will let you know. Thanks again for your help!!

The engine light is out because you reset the computer by disconnecting the battery and the ECM(the computer).

Plug "vcim" into the search box. There is at least one good thread about this PI. However, it is probably not your problem.

You may have more than one thing happening here.

I'm thinking you have a bad coil on number four cylinder and maybe some carbon build up.

I would guess that if you fix the p0354 code and run some fuel cleaner through it the others may go away.

Thanks again for everyone's help. This is what ended up working. No more engine light. Yay!!!

If you guys don't mind I would like to pick your brains again. When I'm at a red light or stop sign or just at a stop. My car sputters and shakes. Any idea what might be causing that?
