How easy should the idle screw on the throttle body turn? I can probably turn this one with fingernail.
Tryin to troubleshoot poor idle / acceleration stumble after a warm start only.

Not that easy.

Back it out all away and remove/chip the old gasket out. Then go to your autoparts store and have them find an injector o-ring that fits right. The rubber should extend beyond the groove so it makes contact with the throttle body housing.

shouldn't turn that easy. on my truck (and a few other people who read my post) I had issues with the idle screw being looser than finger-tight, which would let it randomly spin with engine vibrations. caused weird idle issues where the truck would shut off. I didn't even know about an o-ring at the time and just reinstalled with teflon tape on the threads - been like that for several years.
