weird problem
what would cause a motor to run better with the #2 plug wire removed? on the way home from work yesterday, noticed that it was missing well at least it felt that way but its just idling weird sounds loopy. once you pull the #2 plug wire it runs smother. all others is just misses.
tested.... tps, ecm, coil, plug wires, newer cap and rotor, plugs even look fine
engine has less than 150 miles on it, just built it last week ran great before yesterday
comp test puts it at 180psi on all 4 holes
next guess is the distributor

okay, bear with me a moment...
#2 intake valve is slightly too tight, lets compression push gasses up through the valve/intake... other 3 cylinders suck those gasses in and don't combust properly... disconnecting #2 spark plug removes the problem of combustion gasses being pushed up the intake (since there's no combustion occuring in #2 now) so other cylinders now have clean air and fuel to burn so problem goes away.
and maybe I'll amend my opinion depending on what your reply is to this question: why did the engine need rebuilding and what work was done?

yeah you just miss understood. engine i built back in had 350k on it, smoked like a chimney (about 2 quarts a week).
well your suggestion as much as i wanted it to be the valves its not. I even took then a little loose.

well the only way I'm going to figure that out is doing a LDT, but with the motor being this new its going to be hard to tell exactly where the air is escaping. what boggles me is that it still has 180psi as with the others. what you are saying makes since, this is just frustrating. I'm positive that all the guides were in good shape, same with the valves.

ok so this motor runs great now. getting crappy mileage so I'm going to buy a set of injectors off ebay, send them to get cleaned. I need to know what injectors will work. i know that certain years have different plugs on the harness.
thanks in advance

1988 injectors only work on 1988 22re`s.
87 & earlier are one part number, and 89-95`s use the same part number.
You could swap in an 89 intake manifold & injectors, the 89 + intakes are suppossed to be better than 88 & earlier styles.
