Hey I just swapped a b20z in my wagon and I'm having issues trying to figure out why its idling rough... or missing ok so I'll exspain what's its doing and what I've done .
So I start it and it starts like normal but sounds like is missing.. idle is in normal range. So I have done all the things I could think of to figure out what's going on.. I know a motor needs spark and fuel.. I started off by pulling each spark plug wire and found out that the #4 cylinder when pulled doesn't change the idle... so I figured bad plug or wire.. so I replaced both plug and wire.. still have the problem.. I replaced the dizzy.. still having the problem.. so I pulled the plug out and put it to ground and cranked it over, getting great spark to it so I have spark .. but still have the problem.. so I check to make sure I getting fuel and I'm diffently getting fuel.. (seems like a lot off fuel) sparks plugs was wet when pulled.. so I'm guessing I have a bad injector.. gonna check tomorrow but was wondering if anyone had incountered a problem like this or has any advice or points that I might know or might not be thinking of.. I would greatly apprecaite and and all responses.. thanks

    Well I found a wire pulled out of my obd-0 to obd-1 jumper harness figuring it was the problem, so I cleaned up my harness made sure everything was plugged in where it belongs... I still have the same problem tho! :( any suggestions

    switch 4 and 3 injectors see if the prob moves if it dose then the injector is open

    I would start by checking compression. A b20z is a CRV engine right? I remember years ago hearing something about CRVs with valve adjustment/burning issues.
