Hi I am new to the group I own a 2006 Pontiac Grand Prix GT Blue with Black Leather interior and heated seats. This car is my pride and joy and I am so distraught that it is now having issues with not being able to accelerate past 10 mph. I have taken it to 4 different mechanics with no clear resolution in sight. I have spent thousands of dollars and my baby is still parked and non functional. I have changed the throttle body twice, air intake among other things. I hope that this group can help me to find out what is wrong with my car.
