Would a ported intake manifold cause idle issues? I previously had a BBK 58 mm throttle body on my LT-1 and discovered that since my car is an automatic that wouldn’t work so I went back to the stock throttle body on my very poorly home ported manifold. It will stay running at high idle. But as the rpm comes down to 550-500 it stalls. This is regardless of load. If I rev it up and put it in gear it will happily run at 600 and up but as soon as it gets below that it stalls.

Your IAC may be bad in the stock TB. They can get gunked up so clean with TB cleaner. Don't push or pull on tip.

I forgot to mention already have a new IAC installed. I know it moves because it will high idle at 1100 then slowly click down until it gets to 500 and then stall.

BALLSS

you cleaned the carbon out of the cavity the IAC goes in, right?

ZReally

Yes I did. I’ll try to get a video of it tonight.

I'm struggling I hope they're attached because I had to break the 52 sec clip down into a bunch shorter ones in order to even try to attach them from my Iphone.

Yay last one. Car is still searching for idle goes down to 500 and dies.
