Where can I get a new set of two screws for my tps sensor? One has been rounded out and I can no longer safely loosen or tighten it. Would a new sensor come with them? Thanks

Take one out and match the threads at Home Depot and spend a few cents for a new one. If you can't find one with a matching head, buy two if you think they need to match.

 

do a search on this topic as i can remember one of the guys retaped the throttle body to a more common size thread i did it my self and it worked great threw away those bolts made out of aluminium garbage that snap so easily from what i can remember the size was 10/32 but not 100% sure with the size tap

 

I don't know if TPI throttle bodies are the same, but I snapped off the TPS screws on my 89 TBI unit (they're the same cheap aluminum crap). I took it to a machine shop to have the screws drilled out and removed without screwing up the threads. After they got the old screws out, they called me and told me the original threads were some screwy french-metric size, and they'd have to special order an expensive tap. The screws themselves were also a special order item that were ridiculously expensive too. I ended up going to the local nut and bolt supply, and they sold me two stainless steel allen headed screws and washers, and a SAE machine thread tap (can't remember the exact size). Anyways, all this only cost me like less than five bucks, the screws are a common thread size and way stronger, and I haven't had a problem since. Just my .02.

 

Try this. AC Delco screw kit. These #s are on the box.

Made in the U.S.A. BTW the TPS screws you cant buy. They have a weird thread pitch.

I bought this about 3 years ago, maybe they still stock it. You"ll get the TPS, top plate, and IAC housing screws....Good luck.

 

Most of the new ones you buy at the parts store come with new bolts.

 

I remember reading the problem with locating these screws away from the dealer is that they used a weird bolt size. Something like 4.5 mm, not sure what the pitch is.
