Hello everyone,

This morning my car died and the VSC check light came on along with the check engine and traction control.

I started the car and managed to get it home, although it was missing.

I found that the negative battery cable was loose and I was able to pull it off. (Car had recently been at the dealer for repairs after a fender bender and they did not tighten the cable.)

I was pretty happy, as I was sure this was the culprit. Tightened it down and read out the codes;

P0300, 0301, 0302, P0303 (Misfire codes.) Drove around and car still ran badly.

Reset the codes and car ran great again! Drove around for a few minutes and got the codes

P0300, P2240, P2239. Car is missing badly again.

Reset those codes and car continued missing, driving revealed the codes;

P2237, and P2240.

Any ideas? This happened suddenly, so it would seem to be a ground or electrical problem. The fact that the ground was loose is very suspicious.

I can't find any info about the P2*** codes. Any assistance would be appreciated!
