I have a 2003 Chevy Tahoe that keeps giving a Engine power reduction code. I just came back from the Dealer after having the computer re-programmed. At which time it was showing the following codes.P0120, P0220, P0654, P0740, P0785, P1516, P1518, P1860, and U1026. Please help me figure this out.

There is a fly y wire failure. It is either the throttle body, most common or the pedal sensor.

I would return to the dealer and tell them of all the codes. They may have to re flash the unit

The problem seems to have started when I had the engine replaced in January. But sadly the engine was not replaced at a dealer. So is this a wiring issue then?

No, I did not say that. I said either throttle body or pedal sensor.

The flash, I assume caused all the codes?

Thank you Roy, I will get with the mechanic that performed the engine replacement for us and have him check it out. Is there a site or agency that we can call to see if we were overcharged for services rendered?

No, you agreed to the price when the service was performed. You cannot dispute that after the fact

We were told that it would be around $1700 then when he said that it was finished the price jumped to $3900. At no point during the time he had the vehicle did we ever sign a estimate or anything.

Thats a huge jump. He never told you of the add ons? Shame on him.

Did you pay the bill? If you did, that will complicate the matter as you have agreed to the price. Did you sign the work order when you picked it up?

We did pay the bill because we have a newborn that has major medical issues and we needed our vehicle back. I believe I did sign since he wouldn't give me the keys if I didn't. Now we have had the Engine Power Reduction issue since we got the car back. Seems like the Mechanic we have been dealing with keeps jerking us around.

Those parts were from your original motor. Besides, janruary is about 5 months ago and long after the repair. They could have failed anytime.

Your case will be very hard to prove neglect. I doubt you will win. Did you dispute this with the shop?

He says he is trying to help us fix the issue. Today he told me I needed to goto the dealer to have the computer reset according to Tech Service Bulletin 06-06-04-042A. So I took the car in and payed another $100 on top of what we spent on the work the mechanic did in January.
