On the way in this morning my information center started throwing messages at me:

Traction Control Off
Service Stability Control
Reduce Engine Power

Then my check engine light came on and yea, I had ZERO acceleration.

First time I've seen this, anyone have any thoughts/suggestions?! ]]> General Tech Discussion cmw1876 http://www.grandprixforums.net/help-warning-lights-aplenty-36226.html http://www.grandprixforums.net/u-bend-location-36224.html Thu, 09 Sep 2010 07:15:03 GMT this might sound idiotic, what is the u bend? or where is located at?:confused: this might sound idiotic, what is the u bend? or where is located at?:confused: ]]> General Tech Discussion mtz956 http://www.grandprixforums.net/u-bend-location-36224.html http://www.grandprixforums.net/c-question-04-grand-prix-36209.html Thu, 09 Sep 2010 00:53:13 GMT Ok i got a 2004 grand prix with a 3.8l v6 and i have had some problems with the ac and heat fans.

Anyone have suggestions for a best option here. None of the o2 sensors are operating bc the PCM upgrade. Im looking for as deep a sound I can get out of a V6.

I am currently replacing my longblock with another stock piece due to a rod knock. Whe time and money permit I will build the motor I pulled out. I am just looking for some opinions on what is ok and what to stay away from when it comes to zzp products. I have a really good machine shop in town but they are expensive so I was looking at the zzp crate motor as an option. I have also heard nothing but good things about Intense. Any bad things. Where else can I find parts for my car. One last thing does anyone actually make forged rods for these or am I stuck with the L32 rods as my only option.

But due to my financial situation I’m opting to have a used one put in. We have a salvage yard here, that has tons of 4t65e transmission, they guarantee their transmissions for 15,000 miles regardless of mileage, and most of the transmission cost under $300.
Anyway the shop that looked at my transmission, said yes any 4t65e tranny will bolt in but it is best to find one with the same gear ratio’s ect..
So im searching the inventory of the salvage dealer, and they have lots from all kinds of cars…(im trying to do 04 and up for the better 4th gear hub) does anybody know the ratio of a 2001 GP GT? Or have a list of what make, model, and year GM cars carry this tranny with the same ratio?:( ]]> General Tech Discussion nitrostang21 http://www.grandprixforums.net/tranny-ratios-01-gp-gt-36154.html http://www.grandprixforums.net/car-wont-start-help-please-36131.html Tue, 07 Sep 2010 03:12:10 GMT Could it be my fuel pump because when I went to start it would turn on for about 2 seconds then die.
