Idle problem creating others
It seams as though I have an idle problem that is creating several others.
When I first start my truck the idle takes a short time to come down but does not do so far enough and the RPM's go up and down (slightly).
I can drop it into drive (auto trans.) quite smoothly, the problem is when I put it into reverse, it drops in quite hard and appears to actually rev higher. I have already had to install a rear end due to this.
If I drive for about a mile or more it will go into reverse fairly smooth and continue to do so until I park for a while.
I had it in an auto repair shop, of a friend, he could not determine the cause, but in order to save me his shop labor he suggested I change the "Mass air flow sensor" which I did and also the "PCV valve", still have the problem.
Any suggestions would be greatly appreciated
