drove it all AM. worked fine.. tugged a full size van that was in the snow. Had it to the rug. let off. stalled.. thats normal for my truck...

towed the van to tow. not a hi-cup.

Had to boost a car... (ONLY THING AB NORMAL I DID)

drove it home 15 min. ran great.

went in the house for 5 min.

Came out. Hit the key fired. died.... weird...

and it kept doing that . hit the key. fire. die... UNLESS i put it to the rug then it will fire and run. peddling the gas. drop it in drive. and took it for a good hard rip down the road like 1/2 mile max i SWEAR it was faster than normal.

stopped. idled fine... turned around. drove it back that 1/2 mile. stopped. turned it off. fired it up. same die. fire. die fire...

THOUGHTS?

 

I'd start by replacing the IAC.

 

really? is that just an educated guess? i'm HORRIBLE at diagnosing , i can replace anything though.... haha

 

Well the IAC is the "Idle Air Controller." It has a motor in it that opens and closes a valve to control the airflow when the butterfly valves are closed. They are a very common thing to get stuck and if they get stuck when they aren't opened up very far, it will do what you described your truck doing.

 

yeah, i know how they look/work. alright. lucky i have a spare TB and complete 318 out back. Ill let you know when i replace it. thanks man!

 

If the IAC isn't the cause have the battery load tested, I've had 3 Dakotas do exactly the same thing when the battery was dieing.

 

YUP! was the IAC.. thanks man

 

Heve wondered all these years what the servio like noise is when i shut my 90 3.9 off. thanks to you now i know what it is......!!!!

 

Cool! Glad you got it fixed. One comment though... don't be surprised if it dies quickly depending on where you got it from. I had to go through 3 of them before I finally got one that worked for more than a week! Just keep the reciept in case you need to warrenty it out.

 

Mine came from my spare 2000 ish 318 i have out back. haha came in the box of a dakota i bought for the rear end!

thanks again
