OBD-1 Misfire Diag 92 Accord w/H22
My 92 Accord Wagon has had a cold start misfire that is killing me. When I hop in it in the morning to drive to work it will usually start but sounds like a subaru lol. It misses on 2 cylinders and than start to clear up. Sometimes it misses on 3 cylinders and will not start.
Now a little background. About a year ago my Accord started developing a decent rod knock after 230,000 miles. I've owned it since about 210,000. Done all the maintenance, oil change blah blah blah....
So I started searching for an H22 setup, and found a wrecked 97 Prelude SH that I ended up buying for parts. It drove ok, never had a misfire cold, and my Accord pre-swap never had a misfire cold.
Now when I did the swap I changed out all the maintenance stuff, and resealed the motor. The only things that I changed were the ecu, to a P13 (pretty sure its a jdm p13), the distributor, and the fuel injectors.
Now I called the place I got the dizzy from and told them the story, and the sent me another one just in case I received a faulty one to begin with. So I swapped that out this morning........ same result. I can feel on my header that only cyl #1 is firing 2,3,4 are all cold. So I pull plugs, 2,3,4 all wet with fuel and 1 is dry/normal.
So then I thought I'd try swapping in my old Accord ecu, same result. Now short of having 3 leaky injectors causing it to flood. What else could there be. I know the wiring is intact. I guess I could pluck down some more coin for a set of injectors but I'm at an end with this car, and will prob just go pick up an early WRX wagon.
Any ideas? Anyone know of a cheap set of obd-1 Prelude injectors?

I realized after I posted that I will prob just go up to work and grab my spark tester and injector noid lights. Than go to work figuring this out. I still have a feeling that my injectors are bleeding off, causing those three cylinders to flood out when it sits.
had that happen to me. 2 injectors would leak while the car sit. It would misfire like crazy until it burned off the excess fuel. The way I figured it out was to let the car sit over night and then pull the plugs. I found fuel on the 2 plugs.
