Dropping to idle while driving with no acceleration
I have a 2004 GMC Sierra 1500 Z71. I can startup and head down the road
a short piece, after getting up to road speed 55 mph, it will drop will it will me
to reduce engine speed, and it will not have any acceleration.
I will stop and place in park shut engine off count to 50 or 100, then restart
and continue on my way.
