The other day I was sitting in line at Taco Bell. My V started beeping, and saying stabilitrac off, and service stabilitrac. The gauges were bouncing up and down, then the check engine light came on.
Codes P0700 and U0073
The car went into limp mode and would not shift gears. The engine still ran smooth.
I spoke with a friend who suggested it may be a bad ground somewhere. I looked around at what I could find, mad sure connections on the ECM were seated properly, checked to make sure the main ground line was tight. Everything looked of.
I cleared the code, and drove away. Everything seemed to be fine. I drove about 20 minutes. As I came to a stop sign the engine shut off. It started right back up, but with the check engine light on. This time with:
Code P0330
I was only a few blocks from the house so I drove home. To eliminate the knock sensor from the equation for $12.00 I replaced it.
In my driveway I started the car and let it run several minutes, stopped it, repeated, no check engine lights, but it said my tire pressure on my front left tire was 89psi.
I started to drive away, and made it about 4 blocks. Lights on my dash started flashing, stabilitrac started flashing, I put my hazards on and slowed down. My rear door locks started locking and unlocking.
Long story a little shorter, since then I have scanned the following codes:
U0073
U0100
U0073
Then
P0303
P3007
P00c0
C33aa

I did pull the #3 plug, looked clean, no signs of detonation.
I attached pictures of the scanned trouble codes. I've looked around on various websites, a haynes manual repair manual, and ALL DATA, most of the codes don't even exsist. The ones that are real codes, one thing doesn't seem like it has anything to do with the next.
I'm guessing bad ECM?
Any suggestions?
