Re: Acceleration problem

Thanks for the response, Gents. I'm leaning towards a PCM issue, myself, but have no way to prove it yet. I will be having someone come to my house that can help to sort out my issue. I'll post the results when things have been corrected.

My engine came as a "drop-out", complete with PCM, TAC, harness and pedal, from a '05 Tahoe, so I have to assume that everything is correct for the application. The one thing I did notice when checking the pin-outs at the PCM, connector C1 (blue) has a yellow wire in location #59. The Tahoe doesn't use this pin location (empty), and on the LT1SWAP web site, Brendan says this wire is not needed for '03-'06 harnesses. BUT... the '99-'02 harness uses this location with a yellow wire for serial data. I don't know what this yellow wire is run to, in my harness, and am thinking I should just go ahead and sever it
