#6 of 372 2004 Grand Prix starting and DIC problems.
Apr 02, 2007 (8:11 am)
I own a 2004 Pontiac Grand Prix that now has 44,000 miles on it. At about 22,000 my my car would not start sometimes. You never know when it is going to happen, you just have to guess. We've had computer updates on the car but it still does it. Now our DIC computer shows up all the time reduced engine power, low fuel and guage shows empty when gas in tank, no traction control, trip errors and others. Has anyone had any problems like this?

#9 of 372 Unstable rpm that leads to stalling
Jul 21, 2007 (6:01 am)
This last week Ive had a problem with my 99 grand prix gt. Im on my way to work get off the highway and get stopped at the red light. While im sitting there with my foot on the brake waiting, my rpm would rise like the car was trying to go. A day later still doing the same thing the rpm would go crazy then the car would die on me. I have already taken the car to two shops and they both said they fixed the problem but it is still happening. If anyone has had this problem or know anything about it that can help me fix it that would be awesome.

Did you get your problem fixed? I am having the same issue with my 1997 Grand Prix GTP Supercharged. The spark plugs and wires and alternator have been replaced; but the did not help the problem. Please let me know if you have figured it out.
#11 of 372 GRAND PRIX STALLING AT IDLE
Aug 13, 2007 (3:18 pm)
I have a 1997 Pontiac Grand Prix GTP Supercharged with 88,000 miles. It just started stalling while driving along. The battery light comes on and it stalls. It will re-start after. This seems to happen at slow speeds (around 35 mph) and city driving. It has also happened just coasting down a hill. We have replaced the spark plugs and wires and the alternator. I am still having the problem. Has anybody had this happen and fixed the problem? I would really like to know how. Thanks

I am having the exact same problem on my 2004 GT GP2. The only difference is I am not having the DIC issue. What was the solution to your starting problem. The dealer I have purchased the car from is not a Pontiac dealer, and all they have done is cleaned the injectors and reflashed the PCM a few times. I am still having this issue and am getting a little tired of it.

my 99 gt did the same thing. it turned out to be an old mass airflow sensor. $240 later it runs great. This happened because of my intake. There was also a problem with my body control modulater. But i got that fixed as well.
#14 of 372 Same crap help

1997 Pontiac Grand Prix L 3.8 SII POS.
Bought in 1999 for a grip of cash. 3 Weeks after I. Got it, it started to die for no reason at all. I would wait for a few min and it would start. Had someone with me when it did it, so popped hood checked for spark NOPE! Check for Fuel Yep! so the is an issue with ignition system. Then it would start wile I was searching for problem. Run for a week or so then start it stalling crap again. Off to dealer it went $$$$ later no problem found new dealer $$$$ later no problem. this took me to PEP Boys where they Changed CSP Crankshaft position sensor mega $$$ Week later it's towed back in to PEP Boys under warranty new CSP and Module $$$ 8 weeks later towed back to PEP Boys for CSP MOD and 3 new coils. 2 yes 2 FN hours it died back to PEP Boys "Why well under warranty and cheaper than dealer"
Was told when 1 part fails it takes down many OK Now new ECU CSP coils module plugs wires oil filters water temp oil sensor and a battery. Sh!t did I get a new Car. Warp to 2007 I have put 1200 miles on the car since then It sits till I get home Over the road truck driver
so it gets little use, But hey it runs with a battery minder on it, it has not let me down for 5 years. So I trade the hoe in on a new 2006 GP 3.8 SIII that has absolutely no guts at all.
Well, the 06 has to back for warranty work on brakes, Damn thing. They did a lot of recall work on it as well. Well, I am now an in town truck driver so need a car. What do I see? My old hoe right there, There going to scarp her out for parts. Why she looks brand new 67K on her and I loved her. What an ass I was to sell her. So I buy the hoe back and will park the 06 for you know good dates and what knots. Bad idea the hoe has started her crap again. Now I dive the 06 to work white out side white parchment inside am get her messed up so I have to fix the 97 soon 2 car payments and a truck payment too. Don't ask yes semi truck $567 a week ouch. Oh and I failed to tell you I'm an ASE certified master mechanic with 190K of tools and I hate to work on cars LOL.
