Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    3400 pcm in the mini vans

    Probably the dumbest question ever.....so ive had a couple of the 3400 olds silhouettes. They share the same apparant model number transmission as the 3800 gps ive had. Anyway, i know the 3400 is in other gm cars like the impala. Is it possible to swap the pcm from one of the cars into the mini...

    GTP engine temp/ac questions/problems

    Aight. So its been hot the last two weeks in KC, like upper 90's. So the car is running hot--engine temp is getting over 3/4 on the dial, sometimes it gets up to the mark just before the red. First, my car leaks no coolant. So, its full. Maybe it needs changed? Ok, but here's the deal...

    putting cv joint back in transmission

    Ive replaced my cv joints in my grand prixs and my mini van over and over. I dont have to pay for them, though as they are covered under warranty. The axles in question are on the driver's side--the one with the female end on the axle and the male end on the transmission. The brand is was the...

    mystery popping noise front of vehicle

    Well, its a mystery to me. It sounds kind of like a bad cv joint but they've both been replaced. The noise has happened with the old and new axles. Also, both hubs have been replaced. Visual inspection of the control arms--those look fine. There is no play or movement in them. The...

    hot ac when engine temp gets hot

    When its above 90 or so at idle the car will climb up to 210. I've had two different thermostats in it and it happened with both. New 180 and the stock 195. My other two gtp's never did this unless the coolant was low. This one doesn't leak at all though. the fans work cause they come on...

    the previous owner had leds installed in the headlights and in the interior. the ones in the head lights work as designed but the interior lights don't. when i bought the car they didn't work at all so i didn't see what they even looked like. one day they randomly came on and i thought, "oh...

    2001 GTP Special Edition Bonneville GXP Rims

    I've done nothing to the body except clean it and wax it so far. I've only added my HD head unit, front speakers, and amp and sub to the interior. Under the hood I've changed the valve cover gaskets, put aluminum coolant elbows in, cone intake, ZZP 1.0 PCM, Plugs N' Wires (AL 104's) and a 3.4...
