Problems with 2013 Coyote
Good afternoon. I am having major issues and need some input, please.
2013 F150 5.0. 148,000 miles. Bought new in 2013.
6 months ago started running rich and getting cel for bank1/location1 rich condition.
Smelled a little sulphur from exhaust. Had new cats installed. Went ahead and replaced all 4 O2 sensors with OEM Motocraft ones.
truck ran good again for 50 miles or so, then cel comes back. Same reading on code reader.
Local Ford mechanic says replace MAF sensor. Resets codes and it’s good again for about 50 miles. Then same issue.
Drained all fuel from tank, lines and fuel rail in case of bad gas. Same outcome after 50 miles.
Here is a list of all parts replaced so far:
Coil Packs
Spark Plugs
Replaced K&N with new one
MAF sensor
Catalytic Convertors
4 02 sensors
Fuel Pressure Sensor
Purge Valve
Evap Canister Sensor
Engine Cylinder Temp Sensor
Oil Sending Unit
All 8 Fuel Injectors and Fuel Rail
Spark Plugs again because they were fouled
Filled tank 1/3 way full with e85
I know, I loaded the “parts cannon” but the Dealership charges about $300 per hour and I am not rich.
No matter what I do, the truck runs great for about 50 miles and this starts all over again.
Starts smoking and stinking. Rough idle and stalling. Goes into limp mode and sounds like it has huge cams in it.
I can reset the PCM when it does this and it runs again with no cel temporarily and then does it all over again.
please, please, please help. Any ideas are appreciated. I can’t afford a new one right now and I’ve been down since December.
