Newb, 3.1 question
Hi, i have a 1992 Firebird with a 3.1 V6. Runs great except for when i come to a stop. If i dont put it into neutral it will stall out. It starts and idles fine. Any ideas?

When was the last time you used fuel system cleaner or even replaced your fuel filter? I had the same problem and that solved it right away.

I have the same problem mine is because I put the 2.8L pacesetter headers on my car. Theres no hook up for the smog pump so I have no smog. MY o2 circut stays open because it does not get hot enough. Mine does it when its fully warm and stalls when im going down a long hill under 40 mph. But lately has seemed to gotten better.

i know my buddy was driving like sammy hagar (one foot on the break one foot on the gas) and all he had was a vacume leak and a leaky valve cover. But he also has a tempo
I know this is REALLY off topic but did we always have this annoying spell checker b4?

I had a similar problem, except I have a LB8 (2.8L 6-banger). It ended up being the fuel pump. I would also stall as I came to a stop (RPM's would just drop), so I had to shift to neutral, give it a lil gas to keep the rev's at ~1500. Although this would happen on and off. Like one day it would purr, and the next time I start it up it starts acting up again...
You might want to be careful because when my pump finally died, I got stuck in a shopping mall parking lot all night.

Sorry about the long time no response thing. I tested around the upper and lower intake by spraying carb cleaner around it where the gaskets are. It raised the idle so Im thinking that this was/is my problem. Im changing them tommorow, so hopefully this will fix the problem.

The symptoms are text book examples of IAC or torque converter lockup solenoid issues.
1st...
Basically when you come to a stop, the throttle body closes, shutting off the air supply to the engine. The IAC meters a specific quantity of air past the throttle body through a bypass passage. When the IAC becomes dirty (from oil introduced from the PVC system, road debris, etc) it hangs up or sticks which can cause the engine to die or idle poorly when you come to a stop.
Pull the IAC and clean the pintle and spring with carb/choke cleaner. While you've got it out, spray out the passages in the throttle body. Also, pull the intake ducting and spray out the throttle bore, open the blade by hand and spray around the bore where the blade sits when it's closed. Also grab an old toothbrush and spray/scrub the back side of the throttle blade. Cost 30 minutes and $1.05.
2nd...
If the torque converter doesn't disengage when you come to a stop, the transmission can cause the engine to stall.
Disconnect the wiring harness from the middle-side area of the transmission. Or, disconnect the lockup harness from the brake switch under the dash. Disconnecting either harness will disable the TCC solenoid allowing you to isolate the issue. If it doesn't die at a stop with it disconnected, but dies with it connected, then you need a $30 TCC solenoid, several quarts of transmission fluid, a filter kit, etc.
I'd put my money on the IAC, but both problems are extremely common with these cars.
