This problem has been cropping up from time to time.

1) Start engine, no problem.
2) As I accellerate away, I feel the RPM drop even though I haven't reduced pressure on the pedal.
3) Revving in neutral feels like the max RPM has been reduced to half of what it should be. WOT gives about 2800RPM.
4)Shut engine off, restart, problem goes away.

There are no codes except the usual 1693. It almost feels like the faulty governor pressure sensor as far as sluggishness, except in neutral the revs are reduced as explained above.

Any ideas??

 

with the 1693, there is anther code in there. some the key thing don't pick up, you will have to use a scanner. try it again be sure and check the pcu & the ecm

 

Get the codes pulled from the ECM to make sure your VP is not about to take a dirt nap! Also check your fuel pressure. Keep us posted
