Looking at a 89 4x4 to buy for my son. Everything seems fine it is a rebuilt motor with just 11k. My concern is when I drove it at a stop it would idle so low it seemed like it was going to die. It never did and the owner told me it never has. Is this an easy fix or a sign of a bigger problem???


Thanks
Brian

 

I own a 90 and it idles low when it is warm. I don't worry about it all that much as its done it since i bought it and I have never ad it stall out on me or anything.

 

if it doesnt go away.. try cleaning the throttle body. had that problem with my civic with the idle going so low that it actually dies. anyway goodluck

 

maybe somebody didnt adjust the idle properly during the rebuild. On my V6 there is a screw right by the throttle body that you can adjust the idle with.

 

Thanks guys I didnt think it seemed major but wanted to make sure everything else on the vehicle checked out except for this.

 

Bought the truck...
We did a tune up cleaned the throttle body which was absolutely BLACK with gunk. Repaced the idle screw that was missing set it and all is well....
Thanks Again

 

you can also adjust idle when a/c is on.(with a different screw)
