My tune is not lean either.
Some causes for the codes I found online:
Vacuum leak, dirty MAF, EGR valve problem, restricted feul filter, bad O2 sensor.
O2 Sensors and when was the last time you changed your fuel filter?
Probably 13-14,000 miles.
Let's change that fuel filter and replace your O2's for the sake of just doing it. Have they seen C-16 Fuel? If so, yes we need to change both ASAP.
Managed to get fuel filter and O2 sensors changed today. If you're going to pony wars tomorrow I'll see you there.
I won't be going to Pony Wars. Taking my son to the Monster Truck Jam tomorrow night. :beer: How did that fuel filter look that you took out and how's the car running now?
