With huge thanks to Tom Shiels, I now have a cel!
(think of Tom Hanks on the beach "I ! have FIRE!"
anyway..Lots of codes.
Black only (stored codes) 21, 24, 35, 13
Green only, and at idle only, just 35.
Green only, rev to about 2000 for 60 seconds and I get:
35,51,33,
and I THOUGHT that I saw 21 one time, but I'm not positive, and have not been able to duplicate.
Researching the archive, looks like I can ignore 51? If I'm reading this correctly 51 is neutral switch?
That leaves in the stored memory:
13 -Cam position sensor or circuit
21 -Coolant temperature sensor or circuit
24 -Air control valve or circuit (exc. Justy); Idle speed control solenoid valve (Justy)
35 -Canister purge solenoid or circuit
And in the test mode:
51 (to be ignored)
35
33 -Vehicle speed sensor (VSS) or circuit _ Why would 33 not be in the stored codes?
Additional info on running characteristics:
The van starts up when cold nicely, though will bog down if I try to drive right away, I need to keep the revs up for a minute or 2.
Then drives pretty nice until it gets warmed up, at which point it misses badly, very low power. THIS is my major problem right now, once warm I can only give it a little throttle or misses badly.
I am assuming the hard start problem, with full throttle required, is because of engine flooding, though this is an intermittent problem, occurring about 20% of the time when the motor is warm.
With the oxy. sensor un-plugged, same result.

This is a 94 ej22 in a 4 speed van.
Intermittent hard start, only noticed it when the engine is warm.
Engine spins nicely from the starter without any hint of starting.
No sputtering, coughing etc, just like spinning it without any plugs.
Only way I've found to start it when it's in this mode is following:
Gas pedal all the way down and held there, after about 10 long seconds it sounds like one cylinder starts to fire, then 2.
With the pedal held down, after a total of 20-30 seconds of cranking the rest come on, sputtering, then full on.
Once running and in this mode, idle is much higher than the normal.
No tach but I'm guesstimating around 1500-2000.
As long as the idle is elevated like this, I know that if I turn off the engine it will require the above method to start again.
This may last a day or two, then disappear for several or 6 months.
Ideas of possible causes would be appreciated!
