Thanks for the answer about replacing the exhaust back pressure sensor
However, it did not work.
Just to go over the problem again, when I start the truck up, it idles okay, but when I mash the throttle the RPM raise slightly slower than they should. It idles good .However, when I put it in drive, it idles rough, if placed in park or neutral it idles good again. when I put it in drive and try to go... it has very very little power.
