Engine Performance problem
1998 Ford Ranger 4 cyl Two Wheel Drive Manual 248000 miles
Hello I have a 98 ranger with a 2.5L 4 cylinder. It jerks when I go past 30 kinda stops once I get it past 70. It Idles rough and below 500 rpm for a few minute after I come to a stop or I push in the clutch. I have changed the plugs, wires, and O2 sensor. I have checked the vacuum system and haven’t found any leaks. My engine light came on and the code was P0171. I have found it runs a little bit better at night when it is cooler. Any help would be greatly appreciated.
