More Code 2111

The car had the distributor gear failure shortly after I got it, so
there's a new distributor (and brass gear) in there now. I've loosened
up the distributor and moved it around slightly to see if it had any
effect. Light didn't go off from that. So a code 2111 can be from the
timing window being off? If that's the case, I'll definitely look in to
checking the slack in the timing belt and chain.
I had the MM hose blow out on me, and have been waiting for another one
before I drive the car again. When I do, I'm going to put an O-scope on
the RPM sensor and see how it looks at the ECU connection. Worth
checking out as well :o) Thanks for the tip. When I'm back on the road,
I'll update everyone on the diagnostics.
