So the plot thickens!!!!
Compression check is good. 225psi.
I have been resetting the ECU at the beginning of every test I do.
Still getting P0011 & P0300/P0306 codes and going into limp mode right away if I rev the engine.
So I dive into checking cylinder 6 coil and spark plug. NOTHING. NO SPARK AT ALL. I pull the coil and plug from cylinder 4 and test it on cylinder 4 wire and it sparks. I put the coil and plug on the wire to cylinder 6 and crank. NOTHING.
So now my mind is blown. Apparently my oil wasn't low enough to damage anything. My misfires started a few weeks back and now this. I think I have an electrical problem not a mechanical or sensor problem. Now to check for open circuits.
This all sounds like the same problems many have had in the past that have been unsuccessfully diagnosed or fixed like in this thread:
Ignition Coils Misfiring anyone?
I dusted off the scope and I'm going to dive in to the wiring.
To Be Continued........
