2001 Ford F-150 4.2 V6, with 99,945 miles. Revving at idle. sometimes lerching the truck and have to kick it into netral, has actualy died a couple of times and then sometimes just a mellow revving increase. When it warms up it seems to clear up most of the time? I am getting faults for bank 1 and bank 2 to lean but I am lerry to change both 02 sencers for I am finding it hard to believe they both went out at once. could there be something else causing this? Thanks for the help!
Notorious for vacuum leaks from failed hoses/tubing/conectors.Some of these are very hard to see/access.Check for this and be sure fuel filter is fresh. Look at fuel pressure. Check MAF sensor for dirt that has bypassed air filter. Good luck! Rate me please.
