Because Pro-Flow couldn't seem to get their calibrations straight, I was forced to run with a bad MAF for a couple months until they could custom calibrate one for me. This "bad" MAF was causing the car to run rich enough that it was tripping a check engine light and the code for running rich in both cylinder banks. I finally have a new MAF that works great, but I am wondering if it would be worth my while to replace the plugs for possible fouling. I had to drive the car like this for at least 1000 miles, maybe more. Anyone with decent knowledge please let me know. Thanks.
