I have a '94 F-150 5.0 with AOD transmission. When I put the truck in drive the engine dies. I can drive it in reverse ok. Engine runs in park and neutral. Please help!!

 

Does it die immediately or do the rpms go low then it dies?

 

It dies immediately

 

Sounds like you might have a vacuum leak or or maybe need to clean the IAC. Start the motor and disconnect the IAC, if the engine starts to stumble the the IAC is working.

 

Thanks Mike. I am not sure what the IAC is. Can you help me some?

 

The IAC is the Idle Air Control. It's job is to maintain a steady idle rpm by varying a air bypass around the throttle body butterflies. My engine is a 351W, but it should be in the same general location on a 5.0 I believe.





1990 351W with E4OD, Cruise, and A/C

 

Thanks Island Time for the information and the great picture.
