Sounds like a venting problem with the gas tank. There is a vent for the tank that could be blocked and not allowing pressure to equalize.
Like sucking milk from a bottle without allowing it to vent.
The vent could involve the canister purge system.

SOURCE: The turn signals on my

You have two separate flasher devices on your car. One operates the flashers, and the other, usually located near the fuse area, operates the turn signals. A trip to your local Autozone or Advance Auto Parts, or for that matter most reputable parts house will give the exact location of turnsignal flasher, and they can supply a new one.

SOURCE: can't get gas to go in tank, and it will spit out gas

Every gas tank has a vent tube, so when you fill the tank, air can escape, while the fuel is being pumped into the tank. Some vent tubes are metal, some rubber. Yours is either collapsed or plugged up. Look at the fill tube in the firebird and follow it from the gas cap to the tank, there should be a 2nd smaller tube that is your vent tube. Check to see if it's collapsed, pinched, or bent. This is definitely your problem. Check out this web site for pictures of different fill and vent tubes to get an idea of what to look for. Good luck let me know how you make out. Curt

SOURCE: engine codes p1518, p0125, and p0420 for 2001 firebird

P0125 sets when engine coolant temp does not reach temperature for closed loop operation within a set amount of time.
May be a faulty sensor or thermostat.
P0420 Is related to a faulty rear 02sensor.
P1518 PCM & TAC module communication detected missing or invalid serial data.
If TAC related repair has been done, clear DTC & recheck system. It may be necessary to preform clear codes function twice to clear this DTC.
make sure starting system & charging system are functioning properly. Low voltage can cause this DTC to set. This should help. Let me know how its going.

Having problems with my 1998 Pontiac firebird. When I sit with the air on my car sometimes start to shake or even smoke. I don't know if it's the exhausts or something dealing with it breathing. Whatever...


A bunch of things can cause this.
It could be the engine idle speed is too low, can be caused by a faulty Idle Air Control valve. Watch the rev counter when it does it and see if it's very low. See if it rises when you turn off the air con. The air con puts a load on the engine which should be adjusted for by the IAC valve (automatically opens the throttle very slightly to keep the engine speed from getting too low).
Also possible to be fuel pressure, Mass Air Flow sensor, ignition coil, spark plugs or even a blocked air filter.
Is the check engine light on?
Try looking at Pontiac firebird forums. Google search firebird idle faults. Good luck.

1996 pontiac firebird when I push in on the clutch the voltage meter goes down and the engine dies


I would check out the clutch itself, plate, pad, cylinders, etc. But it could be something as simple as it idles at waaay to low of an RPM, which that is a simple twist of a screw to fix.

I have a 91 firebird with a 3.1 v6. It will idle fine when I first crank it and run down the road fine. But after driving maybe 5-10 miles it will stall anytime I let off the gas. It has a manual...


The first thing I would do is try to relearn the idle. To do this, first disconnect the negative battery cable for a few minutes, then reconnect the cable. Then using an unfolded paper clip jump terminals A and B in the connector under the dash near the steering column, then turn the key on for about 5-10 seconds, and then turn it back to off. Remove the paper clip. Set the parking brake, and make sure everything is turned off, radio, heater, everything. Then start the car and do not touch anything. Let it idle until you hear the cooling fan come on and then go off. Then turn the ignition off. Process complete. If this has no effect on the cars idle, it's time to replace the idle air control valve and clean the passages in the throttle body. As a side note, you really don't want to have to replace the fuel pump, That involves removing the rear-end and the exhaust system from the car, your fuel tank is located above those assemblies.

The turns,hazards, high/ low headlamps, possibly cruise cont. and wipers, are all operated by the "multifunction switch". Replace it and you should be good to go. I hope this helps.

1995 pontiac firebird formula v8 idle


The idle speed is not adjustable, it is computer (PCM) controlled, you can turn the screw for the hard stop, but the computer will just over ride that adjustment for the most part, what I think you may need to do is clean the throttle valve and the idle speed control air bypass valve, use carb spray, spray it in the intake with the engine running use the at least 1/2 the can, the engine will try to stall, keep it running, after you are done disconnect the battery for 10 minutes, reconnect and drive a few days so the computer (PCM) can relearn your driving habits and set the idle correctly based on your driving.
