We have a '03 Pontiac Grand Am GT, 3.4L (3400).


If the resistor bypass doesn't solve it, another remedy could be a plug-in type engine block heater- I mean plug into household current. It keeps the engine coolant warm in the block. Every other car here in Montana uses one-works great for those below zero nights. When the wife pulls into work, just run an extension line and keep the car plugged in till time to go. Other than that, IDK, sounds like you've covered it pretty well as far as solutions.

1999 Grand Am 3400 V6 misfire. replaced plugs, wires, injectors,coils Pull heads to check valves, good compression misfire at idle and goes away above 2000 rpm any help or ideas appreciated


check crankshaft and camshaft sensors. If faulty they may cause misfires, poor fuel mileage, stalls, hard starts. Make sure the ignition coil is ok, including its powers circuit. hopefully this helps!!

If white smoke is coming out of your tail pipe is is burning antifreeze. However have it checked closely. While it could be a head gasket, the 3400 is noted for the intake gasket leaking. Have a pressure test done before you pay for something that you don't need.

Also there is a way to permanently repair the head gasket if it is a real leak as long as it still runs. Check out Barr's Leak head gasket repair and follow the directions to the letter. do not skip any thing. It works I have repair a dozen cars with this.

Hope this helps

Sounds like a dirty mass air flow sensor but the hill thing is strange...Is the tank full when this happens? Could be a filter and would not hurt to change it (often neglected).
