With that said, it seems like your map sensor is bad, or the wiring is messed up. Could be the vacuum line routed wrong too. Crank angle sensor, make sure you don't have the wires hooked up wrong on the distributor. That, or once again, your distributor may be bad. Lastly, intake air sensor. Pretty useless sensor in my opinion, but it's easy. The white plug on the intake manifold, probably not wired correctly or something simple.

What's a cam sensor? I have never heard of that. Crank angle sensor is a sensor inside of the distributor. They are hard to replace and it's better to get a new distributor for that. Or it could be a wiring mistake.

Re: dohc zc cel help
CYP sensor is mounted on the end of the exhaust cam.
Either way, it would throw a code 9. Not one of the codes listed by OP.
(FYI: when people want to NOT use the DOHC cam mounted sensor, they can use an 88-89 Integra distributor with the internal CYP sensor)

Re: dohc zc cel help
You many want to check to see if it was a dpfi and converted. The map sensor wiring may need to be re-pinned. That our your map sensor is shot. I check the IAT sensor too while your at it.

Re: dohc zc cel help
The 88-89 Integra distributor is like an 88-89 crx dx one except you need to run the 2 wires from the exhaust cam sensor to that it wires up like an 88-89 crx si distributor to work correctly. So basically you need an si distributor plug but then wire the dizzy up like a dx and then add the wires from the cam to make it all work.
