If a 2111 code can come from the signals being out of sync, I'd agree
with this fully. When my check engine light is on, under certain loads
(usually acceleration) it will turn off. However, when I had a slight
distributor misalignment previously I was getting a code 2113.
Now that the car is running again (Thanks to Chuck for his old, but
good, MM hose!) I'll get the O-scope on the RPM signal to see how bad it
