i need help locating replacement rubber "o" rings, bands, &/or boot
for the cold idle valve piston (syringe) which is in the throttle body intake.
(a completely loaded replacement piston would work as well)
these rubber parts are missing & i do not know what they look like.
according to gm...these parts are discontinued so......

please assist, thanks

Well, since the 350 5.7 isn't a Northstar engine, this is really not the right forum to ask. Click the link below and post it in the 5.7 forum. I suspect you'll get much better results.
