Truck ran well for like 6 months after replacing the crank position sensor, now the 300 code again and the misfire is back.


Specs of truck.
6L 4L80, 2 fuel tanks, dually flatbed 4wd.

Maybe its time for a blower motor into this 3500 4wd Chevrolet Silverado.

Motor mounts
Headers
Accelerator pedal
Transmission adapter ?

New 4 core Brass radiator.

What am I not considering ?
