Cars runs crappy, Data scans show nothing
About 4 months ago my car started mis-firing real bad, I replaced plugs, wires, cap, and rotor with stock replacement stuff. all is good for about a month. Then one night I turn on the heater and the car starts stumbling, turn it off everything is okay. So I haul out the laptop tonight, and run craig moates software and go for a drive, nothing out of place, except im running a little rich. Problem still persists, heater on car stumbles, turn it off everythings okay. Any suggestions?
