Question about 1993 Pontiac Firebird

1 Answer

I have a 1993 v6 3.4 Pontiac Firebird and I was wanting to check the electrical wiring going to my erg valve. It is the connector that seats on top of the erg valve itself. It has 4 connectors and I can only get one reading off of the top connector. Any ideas on what the others should be reading.? Thanks Mike

You need a shop manual to know what the teminals are.
If you can take it to a shop,they may be able to use the scanner, to command the EGR on and off,or resolve the problem. You won't be able to do that, as you don't know how the system works

The brake lights do not want to work. i have changed the brake switch under the dash and the bulbs on the tail lights.still nothing. i also, changed fuses.


does the high mounted brake light work? the brake switch has 2 contacts one for the high mount (LT BLUE/BLACK) and one for the tail brake lights. The tail/brake light wire is LIGHT BLUE. the main connector between the brake light switch and the tail lights is C208 which is located behind the rear seat, left side. So if there is power coming out of the brake switch OK and no power at the tail lights, check that connector. Hope this helps.

My 1993 Pontiac Firebird is running hot in less than 5 minutes. Changed the radiator, water pump, radiator cap and hoses still running hot. It seems like too much pressure and it's not being released....


Check the coolant temperature sensor (not the sender). Check that connection is clean and good. If you have electric radiator fans do they engage when car is hot. If nor check the fuse and the relay unit connections (under the front by the left inside fender). If you suspect the relay run a positive wire from the battery positive terminal directly to the fan. If the fan runs check the voltage to the relay and the voltage from it when triggered. If the relay is OK wiggle the wires on the coolant sender.

Searches for idle in closed loop


This could be many things. I had somewhat of a similar problem. Here are a few possiblilites though i wouldn't know unless i knew more. Before i do that though. If you press on gas while in neutral will the rpm drop WAY down and then possibly stall out?

Fuel Injectors might be going bad(least likely but possible)
Erg Valve
Oxygen sensor
Cpu
Your idle valve might be off
Timing might be off because of above.

Like i said i don't know exactally and i'm not THAT great and only someone who looks at it and stuff would know but i had somewhat similar problems. If you'd like to explain more email me darkspawnling@hotmail.com. Just add in your car and firebird or something in the subject. Hope it helps.

Missing, spiting and stalling when the car warms up.


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.
