Question about 1995 Pontiac Firebird

2 Answers

Missing, spiting and stalling when the car warms up.

As long as the car is cool (btw 1995 Pontiac Firebird 3.4 L ) it runs fine but as soon as it warms up to operating temp it begins to spit, splutter, stall out or die at every stop. Then it may even backfire and kick hard when you change gears. I have put a new Maf sensor on it and cleaned out the ERG valve, it has new plugs and the wires are only about a year old. Please help if you can, this car is driving me crazy. Arnold

One think you can check right off is for any cracks in any vacuum lines or holes in vacuum operated valves if they exist in that model year. Just a thought.

with the key on engine off listen to fuel pump,if you can not hear the pump winning ,the pump is bad

if you can hear it,it might be working but create enough pressure
you can rent a fuel pressure gauge from auto store and check the fuel pressure

well its a long shot but it could be your catalytic converter is going bad or is clogged, i have seen them get so hott they glow red. this sometimes can be seen at night by looking under your car after it has ran to the point of stalling and dieing,, if thats the problem the car cant exhaust creating back pressure that robbs power and can cause your car to die.. after it cools the metal shrinks back and the car will runn again untill it getts hott.. i hope this helps

The SERVICE ENGINE SOON light in my 1995 Pontiac firebird has been blinking for about a month and one day it just stayed on. At the same time the engine began to shake and now whenever it starts up it...


If your service engine light is on that means that you can find the problem by having a local garage run an engine diagnostics test,it usually runs around 50 bucks and is much easier than trying to find the problem yourself,and most of the time it is cheaper !

1992 pontiac firebird stalls after going one block


Hello!
There a quite a few factors that could cause stalling but before you start spending any money you could check the Oxygen sensor.Seems that as soon as engine warms up and reads the o2 sensor values things go bad.

1995 pontiac firebird will start fine only the firs time


Sounds like the fuel pump is going/gone bad. When they get warm after running, they get weaker. So the next time you crank it, it's too warm and weak to go.

But when you let it sit, it cools off.

To test, see if you can hear it run and prime the system when you turn the key to the "ON" position.

Even better, you can get a fuel pressure gauge and connect it to the fuel rail to confirm whether or not you're even getting fuel there.

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.
