1999 Ford F-150, just changed oxy sensor had code reset and was told #5 cylinder burning lean and that's why she runs rough. Can you adjust the richness of the fuel even though she has fuel injectors and if so how? Or do you have to change the injector?


Thank you. Dave

You can't as the injectors are computer controlled. Burning lean could be due to the injector, vacuum leakages, valve clearances compression etc. What was the code retrieved?
