Pontiac Grand Prix QuestionsRefine by vehicle
i have replaced ignition module,coils,spark plugs and wires ,but i still get diagnostic code 42
I have a 2004 grand prix that runs rough at low rpms below 1000k. I get codes p0101 and p0068. It seems to run rich. Sometimes it will go into reduced power mode run for 30 seconds then die. I've Cleaned the throttle body and maf.
Lights, radio, and lights all work. Happened after jumping a friends car. Not the starter, Tried a button starter, will not make any sound or no warning. Simply will not start.
I had the throttle body and serpentine belt replaced about a week ago.
The headlights will turn on and off by themselves when the car is just sitting. Nobody will be in the car and it won't be running. It seems to happen at random times. This is very persistent and kills the battery almost daily.
N it was hard to turn my wheel is it my power steering pump n if so what parts will i need to fix it
The guy did a diagnosis and told .e he could not determine if its a blown gasket unless he takes the top of engine apart and charged me 500 to do so.. Did he cheat me??
I'll change the course pack the crank sensor the fuel filter in my car still wont start I took it to 3 people and each person said it's not getting a spark so can someone please tell me what else do I need to do is not the security we done check that so what else could it possibly be please help me?
Then it began to stall then kill. Now it doesn't want to start at all. I have changed spark plugs and wires, and battery. What can cause this problem?
The signal lights on the drivers side work intermittently comes up on dash display as "front signal out" or "rear signal out" thought the bulbs still work. When the message appears the blinker blinks faster. When the fog lamps are on the front signal will not work on drivers side. A couple of times during a drive the dash display will say service traction and service abs. If you shut off car it will go back to working. Sometimes it just says abs or just traction. If the heat is on full and you turn the wipers on the heat will stop working (replaced thermostat already). It looks like lots of random electrical problems to me but I'm not sure where to start looking. Please advise?
It don't do it every time but it happens alot.I mean you can push the gas petal all the way down and it will push out of it.but it a like after you take your foot off that's when it starts going
It happens when I try to accelerate quickly. If I go slowly, I don't notice it.
Changed today drove about five miles car cut off and won't start.
I have a Pontiac grand prix and typically when it's first started or after it has Sat for 30 mins or so on restart engine has rough idle, when given gas steadily it will still lose rpm in which you have to pump the gas again, sometimes it straightens out sometimes it dies and heads up display says reduced engine power and won't restart, where we then have to unhook the battery and wait 10-15 mins, hook back up then restart and give it gas until it straightens out. Mass air flow sensor has been changed.
Track control off light stays on and the RPM drops to zero. Car idles too fast. Key gets stuck in ignition. Can anyone help me?
My radiator fans are not turning on at all. Which is causing my car to run very hot and overheat. I've checked the relays and that's not the problem. I for one do not know how to troubleshoot this issue. I don't know whether I should just replace the temperature sensor or the fan motors themselves.
problem started with no cranking once in awhile then started back firing and stalling.now it cranks but wont start. sometimes it wont even crank.other times starts and runs fine for a while.shows no codes when running.
Downstream ak at map sensor, melted MAP sensor ground wire, fans then shut down,replaced thermostat,plugs melted off.replace the plugs. At 30Mph it was dead in the water. Got it home & pulled codes 141, 171, 300. Replaced Downstream o2 sensor,battery, engine thermal sensor (under thermostat housing). Achieved idiocracy by erasing codes and evading loop mode. Coil check acceptable , correct resistance at plug wire connection on top, continuity though no resistance on bottom of coils. No trigger signal present at ignition module w/ homemade LED tester and engine cranking over.Temp light on Comm..Makes plugged, then flooded sound when attempting to start. Found pcm in 2000 bonneville that I can have reprogrammed for $100, but have recently spent $300 + $7,000 in suspension,steering components, cabin components instruments and tires and wheels, prof. body work+ have much love into it. Is there a temp sensor capable of causing shutdown or no start, or could it be a knock sensor
Ticking type noise in the motor at high acceleration
