Stripped plenum-to-lower intake; new lowerintake. or tap blt

[grandprix34]

Should I buy the tap for the 1st small lower intake bolt? ALl the bolts on the plenum are set nice and tight, but the 2nd bolt (1st small bolt) keeps spinng and I know i stripped the thread.

Can one plenum bolt not tight down cause any kind of vacuum leak? Currently I'm having an issue at startup and sometimes at stop lights/idle where the car begins to die and sets a high idle code. Sometimes it doesnt set a code at all, just stutters and dies.

Another question is whether its better to just buy a lower intake off of someone or buy the tap for the lower intake bolt AND the coolant to heater hose threads (since i broke mine inside and used a drill to destroy the remainder of the quick disconnect coolant thingy).

I'd get a tap and bolt it down, I've heard it could cause a vacuum leak. There were people talking about this with grinding the metal bit with the bolt hole for changing the dist. o-ring.

You might be able to find the intakes though, I think someone was just selling them?

Put in a Helicoil. It's a M8 x 1.25 thread. While you are at it, do the rest of the holes too, then you will never have to worry again.
