the way this thing is acting.........it almost sounds like an IAC issue on the earlier 4-3's.

 

yeah i thought that might be the problem so i cleaned the passageway and still no change.the iac is relatively new. is it possible that it might be bad again? idont really want to just go buy a new one and it not change anything...

 

well theres air entering the engine somewhere, you know that. so the best guess would be either something wrong with the TB or theres a vacuum leak.

 

i appreciate everyones input and help but im still lost. so i think im going to go get a new iac and try that. could there be something wrong with the tb? the back of the butterfly is pretty dirty.

 

yes, if it dosent shut all the way.

 

ok the tb is closin all the way... so i think i will go pick up a tb gasket and new iac, clean the tb as best as possible and see what happens..

i have a book of records of stuff done with the truck and the iac was replaced on 8/7/2010. the throttle body was also cleaned at the same time.(doesnt look like its ever been cleaned). i dont have the sixty bucks for a new iac and i cant find the reciept so im not gettin a new one yet. but i will go get a tb gasket so i can take that off and clean it. i will come back later and report what happens.

 

if your IAC was just replaced last Summer, i can't see it being a cause to the problem. but it would be worth taking it off to inspect it, while you're cleaning everything.

 

i didnt think that the iac was the issue. although i do agree that it does sound like an iac issue. i am hoping to get around to pulling it apart tonight when i get out of work.

 

alright i jus got done cleaning my throttle body. i replaced the gasket and cleaned everything up real good. i only started it, havent drivin it yet but it seems that the problem has been resolved. it revved up pretty high when i started it, i then realized that i forgot to put the vacuum line on the back of intake tube but i put it on, put the truck in drive and it didnt rev up like it was. i will drive it in the morning and come back on to report the results. thank you everyone for your help!

 

just remember to turn the key off if she starts to get out of hand.


hopefully the next thing we hear is............."she's golden!!".
