Help What's Wrong I just finished swapping an LS1/A4 into a 69 Camaro. I have been driving it for about a week now. It ran strong at first but now it idles rough and feels like it has no power when you get on it. The computer was reprogramed my S&P and the only codes it's pulling are cooling fan 1 and 2 are not working. I thought that it might be the fuel pump but it is putting out a constant 55psi. What could it be?
Re: Help What's Wrong I think that your fuel preasure sood be more than that.?I had a similar problem and mine was the hose that connects the fuel pump to the main fuel line had a little crack in it wasn't getting all of the fuel it needed.

Re: Help What's Wrong I'm a total amateur, but, do you have an IAT sensor installed someplace in your air intake?
I didn't have one, and although I never really drove the car around, I had been letting it idle, driving around the block, etc. It seemed fine and then a week or so ago it started to idle like crap when it got up to operating temp. Exhaust would go clear/black/clear.
Then I realized I had no IAT. Bought one at Advanced Auto parts (surprisingly) and installed it in my air intake. Could be coincidence, but now it seems to idle smoothly (although again, I still have yet to actually drive it anyplace).
