    2000 Grand Prix GT Idle and Hesitation Issues

    So my 00 Grand Prix has had small idle and hesitation issues for longest time. I loaded the parts cannon many times, no change. I finally got my hands on a serious scan tool. Messing around with the scan tool and the car I have discovered the following. Idle adjusts constantly, it small...

    2001 Chevy Venture No Crank

    I have a 2001 Chevy venture that won't crank or even try to. All the gauges come on and work, along with the hvac controls and radio and all that stuff, but turn the key and nothing. Battery is fine, all fuses are good, however... several fuses are not RECEIVING power. They are not actually...

    Various Issues with the 00 GP, might have finally figured it out?!

    I have made a few threads months back about my car and the odd things it did. A recap, unsteady idle, hesitation on pullout but only occasionally, hard shifts under moderate throttle 3-4.5k rpm, Hard/long starting. Anyway, I had mentioned that i found UIM bolt sitting on the intake, not threaded...

    A/C issue with the 00 GP

    So the A/C in the 00 GP is giving me a weird issue. I turn the A/C on and compressor clicks on, passenger side vent and passenger side center vent get icy cold, but the other 3 barely get cold at all. This improves only slightly as I drive and become just slightly cool. Heat seems to work, fan...

    Coolant Elbow replacement gone horribly wrong

    I saw the notorious plastic elbow on the 3.8's was starting to leak. Original at 160k miles, makes sense i guess. So took the alternator off easy, all the tensioner bolt came out fine. The tensioner was stuck on their like glue still. So I consulted youtube and they said just work at and keep...

    What have you "Jerry Rigged" on your car?

    I'm wondering what "creative" fixes everyone has done to fix their cars, whether said fix has worked, or only worked for a short time, and whether it be to save money, or just out of sheer laziness:th_thumbsup-wink:.

    00 GP More Strange Behaviors

    Well i have made two older threads regarding this car and the little what u may call "idiosyncrasies" it has. Front high idle when you first start it, to a unsteady idle when warm, to goofy transmission behaviors. Well this happens to be another goofy transmission behavior, but a much more...

    98 GP Signs of Trans trouble

    So my parents 98 GP is starting to have transmission issues. Car has 158k on it, but really has not be taken care of all that well. Trans fluid was changed 1 time, but way later then i should have been, i'd say around 130k maybe even later. So last week i was driving it, using my GPS, and the...

    Odd transmission behaviors

    Well on my 00 GP when I drive it cold it doesn't seem to shift to 4th or OD, I can be going 45-50 and it won't, if i let off the gas the rpms go down like its in OD, but i get on the gas even just very slightly it back in 3rd again. Its very smooth, and when it warms up a little bit will stop...

    03 Grand AM wheel bearing-like noise

    I replaced the drivers front wheel bearing and noise is still present. I noticed when i spin the tire in neutral i get a high pitch screech from in toward the transmission, on both sides. If i stick my head in the wheel well it sounds like its from in there somewhere, not the wheel bearing. If i...

    2000 Grand Prix, rear speakers not working.....

    I wondered why the sound system didn't seem very powerful... and i turn on the balance or fade and sent it all to the back and I had NO sound at any volume. Only the front 4 are working. Any idea's maybe fuse or bad connection, i'm not good with wiring stuff. I fiddled with radio settings but...

    Is the LG8/3.1 engine any better than the LA1/3.4 GM engine

    I'm wondering if the 3.1 engine is any better than the 3.4 by GM. A 2002 Montana has blown engine 3.4L and i would like to replace it. I know the 3.4 is notorious for head gasket issues. Does the 3.1 have the same problems? If they are any better, how much would I have to change around to put it...

    2000 Grand Prix, high idle or normal?

    The 2000 Grand Prix GT I got recently has a high idle in my opinion, when it's first start after cooled down completely, like when it sits overnight. The idle is normally around 1700 RPM's. The idle comes back down then after 30 sec, maybe a little less. The reason I think its a little weird...

    2002 Pontiac Montana Head gasket? Maybe?

    Ok, here we go........ my grandma's van. We thought it had a blown head gasket, well a mechanic told us that anyway. It would get to running temp and keep going up. It would smoke on start up but then mysteriously go away. We ran a compression test on it and it was just fine. No film on the oil...
