Engine Mechanical problem
1986 Ford Ranger 4 cyl Two Wheel Drive Manual
My 4 cyl. Ranger won't run( can't tell if it's flooding or starving) between idle and full throttle after it warms up. Idles smooth and wide open seems fine. I have replaced the egr valve and positon sensor, map sensor, all temp sensors, throttle position sensor, oxygen sensor, fuel pressure regulator, tuned it, the computer and even the wire harness. After each item change it will run wonderful for a few days and then right back to won't run between idle and wide open. I love the truck and hate to junk it but am at my wits end. Please help.
have the same problem?
