just wondering if someone could help me out here. if i give the truck a quick rev in park the rpm will idle back to a little less than normal. sometimes it come back quick sometimes it takes a while. i think i was reading somewhere a little bit ago that it might be the ipr is dirty. i had cheap o-rings on the injectors that were put on by the previous owner that failed got them all replaced and installed everything a while back but i noticed this after that happened and it has seemed to get slightly worse since then. used to come back to normal sooner now its taking longer. i know im due for an oil change. could this also be a reason? truck starts normal and drives normal.
