[V8] Hard Start When Warm

[Bob & Missy]

1990 V8
Car is hard to start when warm, even 5 minute trips to the grocery.  If the
throttle body area is fanned a little, it seems to start earlier than
letting the car sit.  I found the following codes and some info about them
by googling around a bit:

2112
Timing (62 degrees BTDC) reference sensor
Flywheel pin damaged/missing,
Mislocated Sensor, flywheel pin, distributor hall sensor out of adjustment
Timing reference sensor Flywheel pin damaged/missing
Ignition reference sender

2113
Hall sender in distributor
Distributor alignment, faulty sender,
Mislocated sensor & distributor.
Hall sender in distributor Distributor alignment
Hall sender - No speed signal from distributor; check Hall sensor and
circuits or the  Air-flow sensor plate is not moving freely; adjust
potentiometer or lever.

Is this a problem with the infamous crank position sensor, or is it a
distributor problem?

	Thanks in advance,
