2 Answers

Hi I have a 1994 firebird v6 3.4 liter engine, my engine light goes on when I drive at cruse speed 55 mph. the engine always runs smooth and when I stop the car for 1 minute and start it again the engine light is off and my not appear for days and in the city the light does not go on only at crusing speed on the highway. I think its the anti pollution sensor, is it the same as the oxygine sensor??..I think I have 3 of them on the 3.4 lt.thanks

Your computer on your firebird is logging a trouble code when the check engine light comes on. Save yourself some money and go to a local parts store to use a scanner. Most parts stores will hook up to your car for free and tell you the codes that are being logged. You can spend a lot of money assuming what parts may be malfunctioning by just throwing parts at your car. Check it first and you will be money ahead.

    It's not an obd2 computer so a parts store more than likely won't have a scanner and key for that exact model.

Engine is stalling when at idle while driving, would a loose ground from battery do this


Get the car up to 55 mph and if the engine smoothes out then replace the EGR Valve.If the engine does'nt smooth out at 55 mph then check the fuel pressure.It should be 41-47 psi with the key on and engine off.

I would start looking for a vacuum leak. Check all the vacuum lines for cracks or breakage. Spray penetrating fluid on them until you hear the engine start to stumble then focus the spray on that area until you are able to pinpoint the location of the leak. Best of luck,my friend, Dana

Transmission problem


car out of cruise control flutters or runs rough from 45 mph to 55 mph and once over 55 mph runs smooth. I notice from 45 to 55 the rpm guage moves with flutter or rough running engine. when i put in cruise control it smooths out.
