What is the sensor circuit B that code P0407 is talking about? I also have a random hesitation on acceleration and Innermitant pop in th eexhaust only. What could cause this? This in on a 2002 F-150 4X4 with a 5.4
I have checked fuel pressure, air filter, fuel filter was replaced 1 week ago. With a stethascope all 8 fuel inectors sound to cycle corectly and the same as do the ignition coils. All the electricla connections are tight too.I did have a bank 1&2 running rich code that went away.
The MAF appears to be functioning correctly as well. The inerrmitant hesitation and pop are only on acceleration. Could ossibly help me with this? I am also unemployed and don't funds right now. Do to eye problems that required 3 procedures to correct over this year. Thank you for what help you can give me.
