Car choking and stalling when slowing down

SOURCE: car over-revving then stalling

check your idle air control motor or the throttle position sensor.

Alot of the new cars have a electronic motor that controls the butterfly valve in the throttle body, that could also be faulty and would require you to get a new throttle body, not cheap, but not outrageous in price most of the time.

If still not sure it would be best to take it to the dealer, they have specialized scanners and other tools that most regular shops do not have.

I had a similar problem and the mechanic diagnosed it as a problem with the ignition coil. So you might want to get that checked.

What you should do is check for spark when the vehicle stalls.If you have no spark then you probably have a bad ignition module.The other thing is You didn`t mention if the check engine light is coming on.If it is then have the codes read.Even if it is not you should still check the codes.Sometimes the computer will have a code and the light will not come on.This could give you a clue as to what could be causing the engine to stall.You might also want to check your fuel pressure just to make sure it is good.The pressure should be 52 - 59 psi.Hope this helps.Good luck.
