Backstory is here but warning long read
Lets talk tests
What are the causes of misfires? Lets go back to basics here.
Talk to me like I have no knowledge and school me on the causes of misfires in the 3.4 V6.
At present time I have pending codes for misfires 1-2-3-5-6 Once I see these it will throw the CEL and die.
Many of the normal items replaced like spark plugs--wires--new coils--Motorwest Fuel injectors--fuel filter--fuel pressure regulator--fuel pressure 42 psi--good compression--replaced a few bad vac lines
So Im not seeing any coolant loss. I have not done a leak down test.
All I want is this thing to get fixed and I will make it a woods truck.
