Engine Performance problem
2002 Ford Ranger 6 cyl Two Wheel Drive Automatic 140000 miles
Ok, so I have had a misfire with cylinder 6 two separate times in 2 years. Both times I replaced all the spark plugs and wires (regular tune up). The code goes away for a while but the truck idles horribly, especially when I come to a red light. I change the oil regularly. I have changed the fuel filter, no change. I have changed the air filter, still rough idle. I cleaned the idle air control valve, and the MAF, and the throttle body. It still idles very rough but was not throwing codes for 2 months just rough idle. Now the check engine light sometimes comes on when I have driven the truck for a while and the engine is very warm, and it ONLY comes on when I am idling at a stop. It blinks until I take off again and then it goes away. I changed the cylinder 6 plug and I still have the problem! I have no idea what to do now!
have the same problem?
