I just bought 93 integra misfiring
 

I just bought a 93 integra and i just replaced the cap the rotor and the plugs and i have a misfire on cylinders 2 and 4 not sure what it can be throwing code 9 if anyone could let me know what they think it could be that would be great.

thanks

Code 9 is a cyp senser (cylinder position senser) Its in your distributer. Did this just happen after you replaced your wires cap and rotor? If so you may have put your wires on wrong the firing order is 1-3-4-2.

just replaced distributor but it just doesnt feel like all the power is there until i hit like 4k it dont wanna go newhere like sometimes i can barely make it up a hill but as soon as i got pass 4k its good but not all the power is there but just isnt a dawg

When you replace the distributor did you reset the base timing? Are you sure you have the rite firing order? Nether will not cause that code but will affect engine performance.

Ok so we have a new distributor so the senser should be good (new new not new to you?). So that leaves 2 wires and the ecm and any connection in between. This is a dumb trick I picked up but grab every wire at the distributor harness, harness end and distributor end and tug on one wire at a time. If one wire comes out of the harness that is the wire that is open. Simple.

More advanced you will need a wire manual you maybe can get one from this site www.hondatech.info do a search. Find the 2 wires going to the cyp senser unplug the distributor and ecm do an ohm check on both wires you want next to 0 ohms not ofl or 100k ohms. Ofl on a meter is open and 100k ohms is very high resistance. Also check to see if the wire are shorted to ground. Take on end of your meter to ground and one to the wire both ends unplugged. You should have ofl.

I would fix the code first. I do not think its a bad ecm probably just a bad wire. Then I would reset the base timing. This should fix the miss problem. crossed fingers.

did a compression test today cylinder 1 had 150 psi cylinder 2 had like 25 cylinder 3 had like 150 and cylinder 4 had like 25

Time for a rebuild my friend

yea i agree rebuild it...
