... since you are seeing both codes I'd start to wonder if you have an issue
with the crank/cam timing. Notice the 2112 code points you this way as
well. You might want to check the dizzy hall sender to make sure it is
functioning ... and if it appears to be so, set the engine up on TDC and
check the crank and cam references ...
