1998 Toyota Corolla LE 4 Cyl 1.80L
what can cause my car to sputter and hesitate when i step on the gas. It also has a slite backfire when i take off.
the milage of the car is 216,000. the proble started yesterday. I had a diagnostic check done, and it said # 2 and 3 cylinder has a misfire also the oxygen sensor gave out a code. i replace all spark plugs an change the ignition coil for the spark plugs but did not change sensor. the car still hesitate and sputter. there was no oil on the spark plugs but it was really covered with carbon and filed down. i also put a injector cleaner in it to flush out the injectors. should i change the sensor , and if so what would be the signs of a oxygen sensor going bad. thanks a bunch.
