1996 k1500 4x4 5.7 automatic misfire mystery
I have never posted for help on a forum before........but I am at the end of my rope.
Multiple random misfires on random cylinders under load.
I have installed new:
Cam Position Sensor
Crank Position Sensor
Distributor cap and rotor
All O2 sensors
Fuel pump and sending unit
Air temp sensor
I haven't had the truck long.....not even long enough to get inspection and tags. I drove it for 70 miles Friday afternoon without incident.....later that evening the misfiring started.
No codes. Seems like it is losing current....the reason I say this is because without disconnecting the battery the clock on the radio resets randomly.
PS: no miss at idle no matter what rpm.
Any input would be greatly appreciated.
