I took off the throttle body to clean it and when I was tightening the nuts back down, I snapped the stud coming out of the plenum. Any suggestions?

Is it really going to be that bad?

 

You may be able to get a set of vise grips on the old stud and twist it out. Then just install a new stud.

 

Autozone sells a set of reverse screws. I have the same problem but with my thermostat housing. The previous owner broke the stud off about a 1/4 of an inch inside![:@] Anyway I bought the reverse out set and predrilled a hole but when I tried the screw it broke off inside![:@] After that I couldnt drill anymore cause the bits are hardened steel![:@] Anyway moral of the story is get a better reverse set, like Craftsman, and drill a bigger hole. Good luck.

 

Well guys, I decided to leave the broken stud in place ( it is the one at the rear of the TB where the coolant line comes in). The only problem I had was that the coolant was leaking out the top of the TB. I just capped off the two hoses. Is there any real danger in doing this?

 

Drill that bitch out.... then retap and install a new stud.... my 88 is so rusty I hesitate to get a wrench cause I know what I really need is the drill and tap set!

 

agreed. drill it out... it's not as hard as you think i will be... just make sure you drill very straight, and do not drill the walls or else you will have a real problem.

 

I brought this up the other week. It was suggested to disconnect your entire EGR system before you cap off your coolant lines to the TB. Makes sense to me, but there are 2 schools on this.

 

If you have mass air, a leak there can cause a idle issue....I would fix it anyway. Try and use a ***** punch and hammer and spin it out....might not work...Put you throttle body on, get a drill the same size as your throttle body screw hole and drill into the screw a little(to get a mark on the center of the screw) then take one a few sizes smaller(tap drill size if you know the thread)and drill it out and tap it. Good luck
