check your fuel filter it could be restricted that won't show up on test. A faulty fuel pump wont show up either...next time it stalls check to see if you can hear the pump running when you turn the key on. (filter may be part of the regulator on top of the pump unit on top but outside the tank)

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?

Key will not turn in 99 Grand Am Ignition


Try turning the steering wheel back and forth abruptly. If not, did you park on a slight incline? My experience has been that sometimes if a vehicle rolls back a little, it will lock it up.
