The dealer pulled the code P0221, which I was not able to with my scanner. You are right, the engine would idle and not accelerate due to a bad foot pedal assembly. Part cost $49.00 at the dealer. Since the powertrain was still under the 5 yr/100,000 mile warrantly, I only had to pay the deductible of $100.

Now it looks like I have problem #1, it won't idle while in drive, so I am planning on replacing the CPS.

Thanks for your help.
