I figured out by looking at a Zurich scanner that it had a code for the throttle body and the throttle body position sensor. The live data showed the pedal was only registering 23% when I had it half way to the floor. So I went to rock auto and ordered a Dorman throttle body with built in tps...
So I discovered that when the new motor was put in they used rtv on the intake instead of putting a gasket there. I've got a metal intake gasket I've been reading that that can cause issues like im having (a bad intake gasket can).
It's still dying. Every one is blaming it on the cam and the 2800-3k stall. If the stage 3 cam is going to cause reliability issues then Id just as soon have it pulled out and a truck Norris cam installed.
Well the damn thing was dying on me when it would cold start. I took it back to the tuner and he leveled out the air flow on it and it seemed to run better until I parked it but now I've got a p0300 code and cell. Plus the dying has started again. I'm going to give him one last Crack at it...
Well the Tahoe has been tuned and it's running great. It feels strong. Right now it just has the stock headers and stock exhaust. The cam is choppy lol.
I had the dude tune it for economy since it's going to be an everyday driver.
Dad was like that motor is not gonna work. He said it's a race motor. I said it's a truck motor out of an 04 tahoe that's been beefed up. He said well if it's a truck motor it won't work. I said what do you think a Tahoe is a car?
