It stalls and dies while driving and while in park. I've changed the plugs the wires an alternator and it's still doing it. I'm lost it only does it after it warms up to running temp. Ive also changed the fuel filter it has fuel pressure checked that the the valve on the motor.

I went over the guides you sent and the throttle body cleaning did the trick I cant believe that would effect the engine but I guess it does.

Thanks for your help ;)
