I have taken it to autozone so many damn time the guys know me by name. After dealing with other issues I still have 3 codes that continue to come up 1. EGR Valve Insufficient Flow Detected 2. Cylinder 1 Misfire 3. Running lean on bank 2 In respect to the problem, I have already changed out the EGR valve, cleaned the throttle body, cleaned out the EGR pipe that connects to the exhuast, have changed both the plugs and wires. And the light goes off for about 100-150 miles then it come back up again. I went to FORD dealership and was told the best thing to do is have them do a diagnostic test on the complete vehicle, only problem is I am running out of time and out of money. I know there is still a number of parts that could be the problem. I was told by my guys at Autozone that it is probably the DPFE sensor which regulates the Air/Gas Flow mixture or the O2 sensor. I just need a little bit more of reassurance before I go and spend all this money and the problem not be fixed. Any help would be greatly appreciated.

Ford had a very bad run of them for a few years.

P0401, I also have the code P0420 come up on mine as well. I found a bad injector on number 1 cyl but don't know what else to do with the other two? way2old Veteran / Moderator Jul 20, 2007, 5:22 AM Post #4 of 5 (5680 views) Re: 2000 F150 V6 4.2 with Service Engine Soon Light on Sign In Please start another thread and give all pertinent information on your vehicle.
