What is the normal operating band for MAF for the 5.4L engine. The MAF sensor is reading from about 0.8 to 1.5 #/minute per OBD2 diagnostic software. I am currently trying to diagnose codes P0171 and P0174 in a 2002 E-150.
No - I won't have time to really work on it until this weekend. I just wanted to see what the MAF sensor was doing prior to cleaning it. I figured if it was reading normal then I might consider leaving it alone and checking everything else first.
