1996 Toyota 4Runner 4 cyl Two Wheel Drive Manual 8000 miles
This engine has 8000 miles on a rebuilt motor. I replaced the Oxygen Sensor and the Check engine light still comes on. I hooked up the diagnostics to the car and was gettiing error code 171 and 3 cylinders are mis-firing. Replaced the plugs, cap, and rotor. The problem still persist.
At idle the engine sputters and at freeway speeds it seems to be fine.
what could be the problem?
