The code says bank 2 sensor 1 stuck lean
1- I checked all the vacuum lines n changed what needed to be changed
2- new spark plugs motorcraft sp433
3- new MSD coils 82448
3- new BNR alternator 250amp
4- new oem o2 sensors both banks, the rear sensors r deleted with sct tuner
5- new fuel filter
6- cleaned the fuel injectors b cuz i bought it 6 months ago
7- new JLT intake
I did all this n there was a good improvement in the car but the code is still comes up if i erased it
On the highway when i go 75mph n up n when i come to a slight climb the engine heat goes up n quickly goes down when i slow down, n i noticed that when i changed the alternator the cam position sensor code was also gone but the power is still weak between 13.1 down to 12.4 volts
I have a 4.10 gears on it so the rpm is high on the highway
Rear cats r deleted but the code is there even before the rear cats were deleted.
I didn't clean the MAF sensor i think if it was dirty both banks will be stuck lean
I contacted marty n he helped me with some diagnostic but still nothing is solved, i took it to an electrician n he saw the o2 sensor connector is kinda melted but not shorted so he fixed the wires but still not solved, any ideas?? Maybe a stuck valve?? The engine is rebuilt but the code disappeared after i rebuilt it
Or bad MAF sensor?? Or the electrician didn't do a good job? B cuz am not convinced by his work honestly, he said there's a power going in the wires but I dnt know am not convinced
I got the valve covers n the spark plugs gaskets needs to be replaced b cuz there was an oil in the spark plugs when i changed them, so i bought a fel pro gasket n l'll install it within couple of days, any ideas before i open the valve cover?
Yeah this code drove me crazy
