Been chasing down ECU code 21 for the ignition primary circuit and I want to rule out lower and upper chain timing on my ka24de.
I did a compression test and got perfect compression on all four cylinders, is that enough to rule out timing?
The marks on my cam sprockets and idler sprocket seem to be facing the right direction as per FSM, but my chain seems to be off one too. Not sure if PO is a dummy or it skipped a tooth
