HI all new to site and need help to increase idle on my 1990 2.3 ranger. Idles at 500 rpm and stalls out all the time,going around corner or just putting it in gear.the screw on throttle body does what? doesn't ajust the idle so why is it there? also the front plug on aod trans is not plugged in as the truck harness is 3 pin and trany is 2 pin, other wise truck is stock with a engine overhaul. thanks for any comments or suggestions. Steve in central Georgia

 

could be a bad MAF

 

Hi what is a MAF? Is this part of a 1990 year model? thanks Steve

 

mass air flow sensor...you could have a MAP sensor instead...not sure which one you have...maybe someone else can shed light on this problem

 

yes I have a map on my truck as it is an older model. Anyone else got any Ideas about what the problem is with this old ford truck? thanks for any help! Steve

 

check for vacuum leaks

 

No No no all you have to do is tighten up the bolt on your throttle body it pushes the throttle out and causes the rpms to increase or decrease very easy and simple

 

thanks Steve
