Since it sounds like this happens infrequently, you may want to check for something binding the accelerator pedal. ( wouldn't that be great if its that simple?) one can only hope...

You may want to have the catalytic convertor checked out. it may need to be replaced.They can cause a car to run hotter and have poor acceleration to the point that the transmisssion won't shift. Also fuel filter could cause this but not usually. Hope this helps please leave comment.

99 Pontiac Grand Prix. When car slows down or


There are SO many things that could be to blame, such as a relay sticking in the Engine Management System, which controls fuel cut-off on deceleration, for example.

Have you changed the fuel filter yet?
If it's the original on a 99 model and a previous owner has run the tank dry, it will have sucked dirt into the filter.

Otherwise, the fuel pump may not be working efficiently.
Does the engine sound ok and maintain steady revs, around 850/900rpm when it's started up?

How do replace heater core in 2002 Pontiac Gran Prix


i do believe you have to take the passengers side dash apart behind the glove compartment. go to autozone and get a manual or go to the library and check the chiltons manual. this is not an easy job. how bad is the leak? if its not bad these heater cores are made of all aluminum. i would buy a bottle of that radiator additive and see if that takes care of the problem first. it only cost about 5 bucks a bottle and it may permanantly fix your problem.
