Yes it worked fine in his truck. Also put my new one on it to and did not help.

No work on the truck. Water water everywhere got us land locked for now and more than likely for a week or so. Going to try to use a tecII to pull data when the water goes down.
Been some time here is the lasted. Pulled the blower back off and put on new gaskets. Old ones looked fine but tried anyway no luck.
OK here is what else I tried today. Tapped off the TB will not run took off the tap and tapped off the MAF will not run. There is a small plug in my inlet tube for the EGR witch the truck does not have pull the small plug and it will run MAF tapped off put the plug back on and die's right off. So from all I have done today I would say there is no vacuum leak. But the IAC is still trying to correct something. The longer I let it idle the higher it goes. Today I let it run for 5min and it went all the way to 2300rpm. Shut it off and pull the IAC and it will run at 700rpm. OK guys jump in and tell me what I am doing wrong.
Did you ever get a scan tool hooked up to it? Seems like you have to figure out what inputs affect the control of the IAC valve. Then, make sure none of them are wacky. Maybe Allen can help here...
I'll admit I don't know crap about tuning, but hopefully someday i'll learn a little...
Do you have this problem posted on any other forums?
Did The valves keep going up. Was hoping to copy them but his scanner would not let use copy them to a PC.The valves of the IAC keep going up now if I am right that says it is opening right so if there was a vacuum leak it would need to close as there is already to much air right. I know were all the wires to the IAC are and thinking of swamping them and see what it dose. Think that would be a good or bad move? May have to make me a 17hr drive to TX OUCH.

May have found a fix. Was talking with a friend from Hilborn injection today and he told me that on some on the newer PCM's THAT THE IAC was wired up different than on the 2002 back. He is sending me all the info pin call outs and all so I can give it a look. He said it would do just what mine is doing so we will see. But after the Power Tour.
"FIXED IT" "FIXED IT" After all this time and pulling what little hair I have out Hilborn came to the rescue. Bottom to wires the Blue ones on the IAC had to be switched. Happy Happy boy I am. Now on to the Power Tour.
that's awesome!!!
but one question, why in the hell were those wires switched, lol?
we sent you a stock pcm with your vin and stock calibration and it still didn't fix it, why would those wires be swapped?
glad you got it going!!!!
get me some feedback and we'll fine tune it.

Here is what Andy told me he had seen a lot of rebuilt PCM that had come out of newer cars and trucks and that they were were that way. Said it drove him nuts until he found it. He said he could plug in a FAST FX box and it would run fine put the rebuilt one on and idle would jump. Got to looking in a little deeper and found it. I pulled all mine out and checked and checked them to make sure they were right that is way I never thought it be in the wires or the box. At least now we know if anyone gets an high Idle to look at the blue wires and see. He said he had found mid year "2002" and newer boxs to being this.
Nice! Glad to hear you got it fixed.
Big slow mud truck with a TUNE!!!!!!
