Question about 2004 Ford Expedition
Truck surges and idles rough, I've changed all spark plugs, cleaned MAF, replaced air filter, Replaced O2 Sensors before the CAT on both sides. No change now brakes just go out. HELP
P2195 & 97 is a lean condition reported by both O2
on right side
The pcm drove the fuel trim lean to correct for a over
rich condition on right bank only due to a leaking fuel
injector most likely
That is a common problem on an expedition with 5.4
I have seen people find & replace the bad injector
I would mail all of them away to be ultra-sonicly cleaned
& flow tested if it were mine
If you have a professional scan tool or software you woulod
see the issue on fuel trim.
The MAF is common to both banks & you only have an issue
on the right side so the MAF is okey
Your plugs should give some indication of the bad injector
if that is the case
Need details on brakes!!
