Re: Having trouble

The 0204 code is an injector circuit, so I think thats a separate issue.

The p0221 and p2138 are dbw-throttle circuit failures. Often that means that the tb/ecm/pedal don't jive, or the potential for an issue with the wiring. I'd take a look at the wires off the TB, making sure your molex plugs are fully seated, and that all the system grounds are adequate.

Are these codes every time, or does it ever work correctly and then go back to fault?
