Engine misfire (rough idle, power loss) and system too lean codes. Tried new coils and plugs, no apparent vac leak. PLEASE HELP
For months I’ve had random misfire problems and engine too lean codes. I changed coils and plugs and it was better for a day before engine light came back on. Rough idle, low power, mpg loss, light will flash when trying to accelerate at higher speeds. Changed PCV valve and hoses after mechanic...- Yorkkidinda831

2005 5.4 navigator issues lean missfire NOBODY CAN FIX IT SO FAR!
So here is where I'm at, I had a master tech look at the car for about a month. The 2005 navigator with a 5.4 misses at idle, pops lean codes on one bank and particularly two cylinders i believe bank 2 and cyl 3 and 5. the other time i can feel the miss is doing about 50mph when i just let into...- coreywsimon
