Trying to replace the idle air control valve on my 93 3.9L Dakota and one of the screws won't budge. It's a T25 head and is very close to stripping. I'd rather not remove the entire throttle body but afraid it's the only way to get any leverage on the screw. Any ideas? Thanks.

 

Spray with WD40, oil it up, and let it sit, crank the next morning. Repeat till success. Patience will get it out guranteed. If you're feeling risky. Crank, spray, repeat. if it strips, make a flathead groove with a chisel. Then use that to crank, also get a bolt instead of a screw to replace it.
