ECU injector driver might be shorted to ground causing an injector to be stuck open. The first symptom to look for are wet plugs....especially if there's one that's wetter than the rest.

Use a noid light (GM OBD-1 I think works for OBD-0 clips as well) to confirm which one is stuck.

Check tranny fluid level. Otherwise check linkage and tranny internals.

 

Ok thanks,How much fluid should be in does it matter becasue when i filled it i puttt 10w40 in it regular motor oil does that matter should i change it 2 some syncromesh or something else let me no please????thanks..

 

Use Honda MTF. Don't ever use motor oil in the transmission. The manual and mechanics might say it's ok, but I've always had problems with grinding gears when using motor oil.
