C&L plenum/TB problems...

Already posted on the corral, but since then I am not able to post any more meesages?? Seems weird, but here is my problem again:

Car will idle for a few seconds then die,,,then restart and it dies, over and over. Almost like a vacuum leak, cause you have to give it gas to keep it running. Once you are on the road driving it is fine, until you come to a stop or put it in neutral, in which case it dies again.

So, bought a new IAC thinking that was the problem,,,helped for like a day, then right back to where it was,,,dying over and over.

So, swapped out the stock TB/plenum and problem solved! Runs great, doesn't die any more. Now, just need to figure out which one is the culprit. Maybe it's the TPS?? The openings on the plenum seem to match perfectly with those on the stock plenum...so....I don't know...

I am not sure what to make of it, so any ideas are appreciated.

thanks...it is a BBK TB (uses stock tps). Looked at all the vacuume lines real good,,,but it runs fine now with the old plenum on. Tomorrow I am going to try to swap out just the C&L plneum and use the old TB, and see if that works. If not, I'll try just swapping out the new TB and keeping the old plenum. Either way, the problem is with one of the two....

I am slowly getting to the problem. Put the C&L plenum on with the stock TB today and it still runs good. So, problem must be with either the BBK TB or the TPS. Not sure what to make of it still. Going to go an try to install the BBK one more time and see if it starts to act up anymore...still could not find any vacuum leaks. Check both ends of all hoses I could find. Some are a little worn, but no obvious cracks. And I even unplugged a few with it running just now and none of them messed up the idle anyways...
