I recently replaced the PCM on my 3800 after recieving a P0117 Coolant Temperature Code and following the diagnostics to the ultimate conclusion.
Now, I have a P0300 and P1200 code showing and the car is running rather poorly. I notice after running the car for at least 10 minutes that the computer is still indicating "open loop" operation. Everything else appears normal.
I am about the follow the P1200 diagnostic steps, but was wondering if anyone might have a suggestion as to why it is operating in "open loop". This seems unrelated to me, but I don't believe this can be unrelated.
Thanks,
Phillip
