I have been having problems with my truck stalling. If I am driving up a hill slow like 5-10MPH and let off when I get to the top of the hill my truck will stall. I thought it would be the Idle sensor on the back of the throttle body. So last night I took it off to clean it. When I put it back in I could not get it to idle at all. I now have it idling. Just wanted to have someone take a look at the video and give mm some suggestions on what could be wrong with it. Also I have a extra sensor I took off a TB I got to mod but it looks different I will get a picture up. If I can just put that one in I will. Thanks for any help.



This one is in my truck


This one is the extra off the tb I got to mod

 

After you cleaned your IAC motor, did you reset the PCM? (disconnect the battery for a couple minutes.)

 

No I didn't reset the computer should I have?

 

Yup.

Computer remembers 'last position" of the IAC. When you reset the PCM, it will forget that little tidbit, so, it will want to figger it out again. Reset your PCM, see if that improves its attitude any. It might take it a bit to re-learn idle, but, should happen within a few miles.

 

I will go do that now

 

Anytime your fooling with the sensors you should first disconnect the negative battery cable anyway. Or you run the risk of doing damage.

 

I though about that after I was done.

 

I reset the computer same problem. Do you guys think the two IAC motors will be the same? Thay have the same plug.

 

From what I can find, 95-98 were the same, 99-01 were the same.... (and the two year ranges are not interchangable..... so far as I can tell) No info at all on the 91-94's..... (I can find 80 something to 91, but, not 94.... the one that advance auto's website shows isnt even an IAC motor......)

 

I put up pictures of the two I have. I gess I could just try it.
