Hello, I've got a 92 pontiac grand prix with a 3.1 motor (148, miles) it was
running fine few day ago and out of no where it begin to stalled at idle and
while driving. it act it like a spark plug or spark plug wire problem. i replaced
them, and the problem still there. no codes in the computer. I notice
that it does this when hot...

It could be a torque converter clutch issue if it "jerks" like a manual transmission car when you forget to push in the clutch when decelerating.

Check the links and posts in my signature file for some ideas.

Does it stall like I described (the jerking when declerating?). If not, it's not a TCC problem.

There's usually a 4 pin connector at the top of the transmission. If you disconnect that and the problem goes away, the TCC is the problem. You can fix it or leave it disconnected for now.

The TCC is not a DIY replacement. That's for a trans shop. If you pulled the plug and there is no difference, the TCC is not likely to be the problem.

How do you know you have an air leak? You need to be more descriptive of the problem.

Again, what do the links in www.autolibrary.org have to say? Did you check the coils? Wires? Module? How's the fuel pressure?

Always start with the basics .
