used to idle at 750 before the motor got replaced.


Vacuum leak or tach error.

Idle is computer controlled. No changes outside of reprogramming the PCM will change it.



not sure if i have reset the PCm since the motor swap.
haven't noticed any vacuum leaks, but i will have to do some investigating.
Ford said the idle seemed fine to them and they couldnt feel the vibration caused by the low idle.
