running rough and shifting funny
I have a 1997 Exp 5.4L 4wd with 169,000 miles.
It recently has started running a little rough. Some times cutting off. I have noticed it has lost some power at low speeds and seems to shift funny. Around 45 mph everything seems fine. The check engine ligt is on and the codes are PO 1131, PO170, PO401 and PO 130. About a year ago I replaced the speed sensor motor because of shifting issues and it has been running good up to a couple of weeks ago. The trans seems to be strong just a funny shifting between gears at low speed.
