The car runs fine at all gears but when decelerating sometimes the vehicle will turn off. any suggestions on what to look for. Standard idle on this vehicle is 750RPM when warm up. When decelerating the idle drops down to as low 200RPM hestitates and dies. This happens around 40% of the time. This happens even if I glide to a stop on nuetral. Any suggestions will be appreciated...

 

are you running your a/c or anything that has a load on the motor

 

i would say check your timming and check your tps

 

clean BAC valve

are there any modifications at all to the engine?
