Hello, my Expedition is spitting 4 different codes. It is a 2000 Ford Expedition 2WD Eddie Bauer Edition, it has a 4.6 Triton with 270,000 miles. Check Engine Light came on with a code for a misfire in Cylinder 7, we replaced the Spark Plug, and it didn't fix the issue. We then replaced the Coil, and that fixed the issue. It had no codes and was driving perfectly fine again. We parked it for a week while we were on vacation, and when we got home and drove it, it started the vibrations again, and this time it is spitting all 4 of these codes. We know that when 1 coil goes out, they likely will all start going out. Replacing all Coils and Spark Plugs is our next step, but the other 3 codes seem unrelated to the Cylinder Misfire. I know it has a lot of miles, but it has stayed very well maintained. Which is why this is so concerning because it all seemed to have happened at once.
CODES:
-P0305 - Cylinder 5 misfire
-P1132 - Lack of HO2S11 Switch - Rich
-P1400 - DPFE Circuit Low Input
-P0443 - Evap Emissions System Purge CVC
SYMPTOMS:
-Check Engine Light
-Severe Vibrations at lower RPMs (1200-1600)
-Misfire
-Check Engine Light begins flashing if driven above 2300 RPMs (going uphill or accelerating)
-Fuel Efficiency Depleted (average of 8.7mpg at this point)
The motor is powerful, no hesitations, no cranking issues, transmission is strong, no overheating, very quiet (I have had numerous Expedition Enthusiasts comment on how quiet mine is), it idles good aside from being able to hear/feel the misfire is Cylinder 5, and honestly if it wasn't for the service Light, vibration, and fuel issues you wouldn't know there was any issues at all. Which is why I believe it is likely an electrical issue sonewhere, as the hardware all seems to be in working order.
Anyone else have these issues? Could 1 thing have triggered 2 or more of these codes? I know the misfire is a big issue, and I know fixing it will help a lot, but the other 3 codes seem u related to the misfire.
