I have a 1994 pontiac firebird 6 cyl 5speed manaul The service engin light stays on. how can I turn it off?


Just thought I should chime in here. I also own a 1994 Firebird V6 that I've been doing a ton of work and research on..I would strongly suggest retriving the code that your SES light is trying to alert you about before you clear it. You can clear all codes by just disconnecting your negitive battery terminal for about 5 minutes then reconnecting it. It can also be done by just pulling you PCM BATT fuse for 5 minutes. BUT...the light will just come back on if it's a problem that still exsists and is ongoing. BTW...my maintenence manuals for this car says to disconnect the battery (or pulling the PCM BATT fuse) like this before doing any maintenence on the ignition, fuel, air intake, vacuum, secondary A.I.R. system, and/or any tune-up work, etc. When you're done, reconnect the battery. Hope this helps.

I have a 1994 Pontiac Firebird 3.4l engine and the vehicle is overheating even after i replaced the thermostat. Not sure where to go from here. Any help would be appreciated


does the electric fans kick on? if you have a/c start the car, and turn on the a/c. this should make the electric fan to come on. if the fan does not come on, then your fan isnt working, which will make the engine over heat when the car isnt moving.
