well i have noticed that my car turns off when i let go of the gas pedal...i move the tps both ways and the same problem.. i check all the vacuum lines and everything is fine. i drove it for a while and it when away. but it keeps coming back.. i hate driving with two feet.anything i need to replace or check. my check engine does not come ON. so i dont think is a sensor failures. i always pump 91 gas. i did a gas filter change and spark plugs like 2 months again. about two weeks a go they change the alternator. my runs good all the time. but is the it idles to look and turns off..

it may be your fuel pump ecu. See the thread just next to this one entitled "car dies.....a lot". Yours may be in the beginning stages.

check your MAF or MAP, I had 2 cars that my family owns that had that same problem. 1 was a MZB E55 AMG and my Sc400.. Both just randomly died. Or when you free rev.
