running rough, part II

[Michael J Myers <mimyers@prairie.nodak.edu>]

All the e-mail messages I got thought it was the cam timing.  So I went 
out and I recheck everything.  Flywheel "O" mark is in the right place, 
dot on back of sprocket is slightly above cam cover.  Pulled distributor 
apart and the two lines in it line up.  Ran the engine for a minute and 
got a trouble code for hall effect sensor.  Ran tests from bentley, 
everything is ok.  Any more ideas?  Engine will start and run. Slow to 
speed up and down.  Will not idle without stalling.  Stumbles (possibly 
backfires) when the engine is slowing down and you open the throttle.
	Thanks
