Pontiac - Grandprix :: 1998 - Starts Coughing At 45 - 50 Mph?
I travel to get to work, and on the way I use the interstate. Speed is posted at 55, naturally, but in the fast lane - the left-most lane of 4 - you have to keep up, you understand. Fast lane is usually 65 to 70.So I'm traveling on the Interstate and in order to use the faster lanes than the right lane I depress the accelerator, and the car - 1998 Pontiac Grand Prix - speeds up, as you would expect. However, when it reaches about 45 to 50 mph the car begins to ... cough. Just a little. If I step on the gas harder so that overdrive kicks in the car stops 'coughing'. As I decelerate there is no coughing, only when I am speeding up and hit that 45 to 50 mph barrier.What is causing this?

I've got a 2007 pontiac grand prix that I picked up off a guy for $900 and so far it's been a head ache. So far, I've had to replace the power steering pump, pump lining, there's a hole in the radiator, and now a mystery problem that me and my lack of car knowledge can't diagnose.
Smoke/steam (smells burned) is coming from behind the engine and when the wheels are turned, it sounds like a high pitched grinding noise. I checked the oil, its fine. I filled the radiator with water as a temporary fix until I can afford to get the radiator fixed or repaired. Air conditioning only works on max setting. Before the problem occurred, I was pouring water into the extra reservoir when my friend started the car. Maybe the radiator sucked up some air while I was filling the reservoir.
Pontiac - Grandprix :: 2002 - Engine Whines When Driving
Recently I noticed that my car is whining when I'm driving. It occurs while I'm in gear driving, not only when I'm turning. I can also hear it when I'm not accelerating and I'm coasting. The only time I don't hear it is when the car is idle or in park.

Pontiac - Grandprix :: Engine Disengages When Headlights Turn On
Turning on headlights cuts engine. Sometimes won't start at all even with lights off. All dash lights go out as well. I.e. when auxiliary is on only radio works, turning on headlights shuts off radio. Recently got a used alternator. Could not find any issues pertaining to the alternator. New battery as well.

I have a 2003 grand prix. Sometimes when i am completely stopped at a light, then put my foot on the accelerator as it turns green, the engine will start accelerating but the car wont move for a second. It then jumps forward in a frightening way. It feels like the brakes don't completely disengage or maybe a belt is slipping. I also notice when I am driving and take my foot off the gas for a second and put it back on the RPMs will jump up about 1000. Im not an aggressive driver or anything at all.

Our 07 Mazda5 (80k) once in a while will start and run very roughly, and pressing the gas to the floor only gets it to 3,000 rpms.It has diminished power for climbing hills when this occurs. Everytime this happens if we shut the car off and let it sit (between 10 minutes - a couple hours) it starts and runs like a top. We have added drygas 2 of the times, but the last time it happened was on the same tank of gas that we added the drygas to. Check engine light comes on, but will go off after a day or so.

Got a 2002 GT with the NA 3.8 and 150,000 miles. The car has pretty much sat for the past 6 months, driven very sparingly. If it's been sitting for a while (like over night or longer) it will start no problem. If I turn the car off for a shorter period, it will crank but not fire. It will start only if I pump the gas as I'm turning the ignition.
In addition, on occasions it has died while at idle or coasting to a stoplight. After it dies it will fire back up no problem.
Fuel problem perhaps?
The "Service Engine Soon" light has been on for about a month before it started acting up. I had the codes checked at AutoZone and it came up with P0442 and P0128.
Pontiac - Grandprix :: Rattling Or Sputtering Accompanied With Sudden Power Loss Then Engine Shuts Off
Ok here's the problem. I have a 2003 grand prix se 3.1 and a 1998 grand prix gtp series II sc. Both have the exact same problem running and both had overheating issues prior to. I can start either one on a given day while cold and drive them as if nothing is wrong. But soon as either one hits operating temp, I start to hear what sounds like a rattling or sputtering like sound from under the hood, accompanied with a sudden loss of power and then the engine shuts off. Now yesterday I attempted further diagnostics with the se model GP. I let it idle rather than driving it this time, and it ran perfectly fine for about 20 mins, started to make the aforementioned noise, I revved the engine to about 2000 rpm and it kept it from cutting off and smoothed, but the second I let up, it was off and wouldn't restart till it was cooled off. Same goes for the gtp. I'm really stumped on this one.

My 1994 TransAm has 70k miles. As I';m driving, I'll notice the tach needle drop to zero with no warning, and the car just dies. Battery is fine, gas tank is full, and it soon starts again and works normally. Friends have suggested the timing belt (or chain?) may be the issue, and one day, it won't start again, or it will break and ruin the engine. She, like me, is an antique -- is it time to take her in to the repair shop, and if so, is it costly?

Engine starts then runs for a period of time until it warms up, then fans come on and then EGR clicks on and off every other second , then it eventually quits. Replaced the coolant temp sensor. And it never sets a code. Have checked wiring for shorts and nothing. Is it a ECM going bad?? When trying to drive it , it will only go about a half a block , then quits , Then will start up again.???

Hottest day ever on Planet Earth and my air conditioner in my Pontiac decides to throw hot air in my face! Luckily, for my female companion, she gets ice cold air. This 2002 Grand Prix 40th Anniversary edition has 236,000 miles, I never once had a problem with the air conditioner in the past (have thought about contacting GM asking what they did right in this car)This model has dual climate control. I noticed that in turning the selector knob on the dash climate control panel, there is hot air in the vent, bi-level, heater and defrost, but cold air comes out on the passenger side. The interior temperature functions are all similar on the '97 through '03 models of Grand Prix, just wondered if this is something I can fix, or do I need to visit a Pontiac dealer to have it diagnosed (and spend a lot of money)

Code is for tcc stuck on. Code p0741 is tcc stuck off. So, it's a sticky solenoid. Which means it may start out sticking occasionally and progress to sticking more often and finally staying on/off permanently? If u get the code/symptoms 1 time, does it usually mean it will happen again, soon?

We were driving home yesterday and all of the sudden the car started to over heat and we could smell antifreeze. We turned the ac off and put more water in it. Today we just had to make a short trip somewhere (we were planning on having it looked at first thing Monday morning). The temperature gauge never showed it overheating but as we pulled into our driveway we heard a knocking sound and it just shut off. Iit may just be a leak and it caused the car to over heat??

View 5 RepliesPontiac - Grandprix :: 2001 - Banging On Gas Tank
We have a grand prix and had the water pump replaced. Soon after this the fuel pump went out. We replaced it 2 more times within a few weeks. Bought another one and this time the car may have run a period of 4 to 5 months before it went out. We have found by banging on the gas tank, and by turning the car on while someone bangs on it, you can hear the pump come on and start the car. Well, once again this week we have had the pump changed and I was about to leave work and the car would not start. Banging on the tank allowed me to be able to start the car... What is going on with the pumps or what is making them go out...???
