Ok I am at my wits end with this car I am about to just get rid of it! We have changed the plugs & wires & coils, and the fuel filter, and the stupid thing is still running like garbage! It's like it's not getting any fuel but yet it's not throwing any codes. You push on the gas & the RPM"s raise but it's not going any faster & then when you let off the gas it feels like it shifts but then it jerks after that like your running out of gas can anyone help me with this?

I have a 2000 Pontaic Grand Prix GT that I am having the same problem. As I am driving the car and as I push on the gas the RPM gage will raise to 3 or higher but the car will not engage. I have to let off of the gas and then the car will shift. Sometimes the car will engage after I let off of the gas but sometimes I have to do that several time before the car will engage. However the check engin light is on and the codes it is reading is PO404 EGR Circuit Range/Performance & PO410 Sec. Air System Malfunction. I have noticed that the car would shift fine until the check engine light appeared. I will let you know if changing these parts will have anything to do with the shifting problem but i do not believe it will help with my problem.

I am having the same problem. I have a 2000 Pontaic Grand Prix with 178,000 miles. I just has the transmission rebuilt because it would not go into 1st gear. Now since I recieved the car back I have noticed that sometimes when you push on the gas while driving the RPM gage will go to 3 or higher but the car will not enagage; I have to let off of the gas so the car will shift and sometimes I have to do this several time before it will engage. I was told that it is an electical problem. I have replaced the computer brain but that did not solve the probelm. I am going to replace the Speed Control sensor next. I love my car also and this seems to be the only problem I am having soI am not giving up. I will keep you updated.

I have taken my car to a tranmission shop because the first gear was out and had the transmission rebuilt. Once I received the car back I noticed that the car was shifting hard and the RPM gage would rise but the car would not engage. I took the car back and they told me it was an electrical problem and they were unable to fix it. I took my car to another transmission shop and told them the RPM gage rises but the car does not engage. I was told it is the torque converter and now my car runs great. Please have your torque converter checked. I wish you luck with your car.

I have a 2007 GXP, Two month ago or so it started with the reduced power message on the computer. got it to the shop that day and they hook up the test and it stated that the peddle sensor was in question. so he reset the computer and the throttle body was cleaned out. It still ran with hesitation. two days ago the transmission was not pulling when the gas paddle was applied and I schedule and appointment with the dealer, on my way to take it to the dealer the trans made a wining noise and I lost all gear, yep towed. It only has 62000 (easy) miles , while its a power plant of a car I dont drive it that way. Im told they will have a answer on friday. But the problem sounds near the same to most on this site . Does GM have any recalls on the transmission or this problem at this time ? The peddle sensor was replaced prior to the transmission failure

I have a 2006 Grand Prix that is a lemon brought it with 32,000 miles on it in 2007 and the car fax report said it had no problems. I have had the hub assembly replace 3 times, the water pump, the powering steering, the trasmission was rebulit at 62,000 miles. I recently went on vacation and the transmission went out again cost me 2500.00 dollars to rebuild it again only 60,000 miles later. I wish I had never brought this car I have never owned a car that had so many problems. Tell everyone to stay away from GM!!!!!!!!!!!!!!!!!
