my car hesitates at the initial start up... if it starts. and while diving, it frequently shuts of when i let off the accelerator, or come to a stop, but starts right back up. if it sits for awhile it while start right up as well. i thought it was a fuel problem so i changed the fuel filter. i also hooked up to the obd2 port and it read codes for mass air flow and vaf sensor. i checked for any vac leaks and noticed a couple small warps on the upper intake (which is plastic) and wondered if that could be it. do you know if this is a common prob with pontiacs? and what would be the ideal way to check for a leak in that area?
