OBD1 CEL Diagnose (chipped p28)
I'm running a 92 CX civic with a b20z/GSR swap on a chipped p28 and safc2 piggyback and my car is down at the moment. I tried the CEL diagnose and when I turned the key the CEL stayed lit on. (when i normally crank the car, it will come on normally for 1 second but with me shorting the diagnostic connector, the CEL stays lit)
Would that mean a code 0???
ECU problems?

Check whether fuse 31, 24, or 18 is blown and whether the ground wire attached to the thermostat housing is loose, disconnected, or corroded.

Re: OBD1 CEL Diagnose (chipped p28)
Ok, i've done a compression test on my engine and cylinder bank 1 shows a compression of 175 psi, cylinder bank 2 shows 190, and cylinder banks 3 and 4 both show 0psi of pressure.
So I proceeded to do a wet compression test (the compression test with oil), and found that there was still no compression in banks 3 and 4, and a real small amount of oil squirted out of the cylinder banks, so that means my compression rings must be good, So I figured I have bent intake valves.
So I was wondering if just getting new intake valves and the rocker arm springs would fix it (wouldn't that be a probable cause of my car throwing a code 3?).
Thanks so much Ron :], I'm still a high school student so don't have such a wide mechanical knowledge of cars :]
P.S. I forgot to add in the first post my car won't idle and to keep the engine running I have to constantly keep it gassed to at least 500 rpm.

So I tore off the head, and found that my exhaust cam is broke after cylinder 2.. and none of my valves are bent.. so i'm guessing all i need to do is get new exhaust cams.. :[
