“2000 ford ranger 2.5l 5 speed manual 2wd. I keep getting code P0171 every couple of weeks.”

“I keep getting code P0171 every couple of weeks. I’ve replaced the IAC Valve and I did find a small vacuum leak.”

“I ran the scanner first and the codes that remain after all that work are p0171 (passenger side) and p0175 (rich on the driver side). I may add the codes are not very consistent.”

“A friend bought this truck with a bad motor. I replaced the motor after that the truck ran decent for 1 day and since then it runs rough and lack acceleration.”

“Hey guys, first off, I have a 2006 ranger single cab, xlt, 3.0, 120,000 miles. manual transmission. Everything is stock except for a magnaflow muffler.”

“I have never had an an once of trouble until this weekend. I got gas, and began climbing the mountain to the hunting cabin pulling the 4 wheeler and trailer.”

“As far as the mechanical I was getting a couple of error codes P0171 and P0460. I replaced the mass air flow sensor which seems to have taken care of the P0171 and just replaced the fuel pump module assembly which seems to have eliminated the P0460 code.”

“In the meantime I made a post at the other place with some more detail, freeze frames and the new misfire code that popped up. And a video of the weird idle and high pitched sound.”
