After it warms up it will slowly take off
Expert:  Chris (aka- Moose) replied 1 month ago.

Once warm in park does the engine respond correct to throttle applied?

Does runs rough mean you are feeling a misfire?

Is there smoke from the exhaust during this issue?

When cold does it operate fine?

Customer: replied 1 month ago.
Every now and then I will have a little smoke it feels like a miss when in gear and hard to start when cold and won't move when cold ipr reading 31.8 icp reading 500+
Expert:  Chris (aka- Moose) replied 1 month ago.

Idling cold and idling rough. What is the ICP pressure reading at that time?

Will your scan tool run power balance test?
