i just put a new egr valve and epv sensor in today. and the first time i drove it it drove great, it idled a lot smoother and didn't buck as much. i took off my negative cable for a few hours to re set the computer b.c. my check engine light still came on. well i parked it and went to drive it again and then it was spuddering really bad and the accleration levels off extremely badly at approx 2.5 grand. the truck turned into a complete dog. it couldn't move to get out of it's own way. my truck is really starting to p*** me off. i have no clue what this could be. i think it is a fuel delivery problem but not sure, so i could use any suggestions. i plan on having my injectors cleaned thursday and i am hoping that will help but still not sure.
I have read that anytime you remove battery power to reset the computer that it may take awhile for your computer to "re-learn" all of it's parameters. Hopefully over a short time it will clear up.
