Wj The good and the bad

Well. I got my new 4.7 engine running, and I fixed the problem I had with the leaking transmission cooler. I will get pictures when I can find my camera. I havfe 2 codes, P10123, and P0113, both i think happened when I was taking the plug off the sensor whole it was running but I am not sure.

My biggest problem though is I start it up and it shuts right off it will run if I keep my foot on the accelerator. I don't have the first clue were to look. I have check every conection, those are the only codes, I also put on a new fuel filter. I will start looking and playing around with it in a few hours.

How much have you run it so far? Maybe it needs a bit more time to run and set itself up/learn IAC counts? Is the IAC new/cleaned? Any vacuum leaks...all it might take is one small hose off or broken somewhere for this to happen.

Id disco the battery and clear the codes so you know for sure.

When the gas pedal is floored its, afaik, opening the butterfly and letting more air in. So maybe theres a problem there.Someone a lot better than i at these things will be along soon

I am getting ready to go out and check all the vacum lines again. The IAC is the same one that has always be on the it, I did clean it though. I had had it running the day before it started doing this. I ran it for about 10-15 minutes, but I had a leak at the transmission cooler. I got some fresh gas, and some Heet to take out any water that may be in the tank. I will see what I find.

It may have just figured out the IAC combinations but do not go too far until you deem it reliable. It is probably was or may still be the IAC. Nevertheless, good luck and enjoy the 4.7!
