Asked by Jul 14, 2017 at 12:35 PM about the 2001 Chevrolet Silverado 2500HD Base Extended Cab

Question type: Maintenance & Repair

Ok so here we go
The truck is random misfire code.
I have changed the following.

Air filter
Fuel filter
Fuel pump and sending unit
All 8 coil packs
Plugs
Wires
Crankshaft sensor
Oil
Oil filter
Cleaned the tank 3/4 fresh fuel.
I have no idea why the service engine soon
light keeps blinking... It will go off time to
time for about a min or so. Any ideas would
be greatly appreciated.
