hi everyone i need some help with a dohc zc i just put on my ef. it was working fine for the first 2 weeks then out of no were i started to get lag on it a bit. like 2 days after the lag started it just died on me it wouldnt even idle anymore, it would just turn off. i checked my plugs and found out that they were all carbon fouled. i tried cleaning them up and and putting them back on but it just fouled them up again. i am using a pr4 on a stock dohc zc. oh and the ecu isnt giving out any engine codes or anything. does anyone know what it may be?

 

this seems to be a comon problem, sounds like the ignitor in the disrtibutor has gone bad

 

thx im gonna try that as soon as i get a chance tomorrow.

 

hey i just replaced the igniter and that didnt seem to be the problem. its doing the exact same. turns on and stuff but wont idle right i have to give it gas to keep it on.

 

i just started to get a code 9 that means cyp right? could this be whats wrong? i really need someones help.

 

it could be a combination of things: you could be running really rich/your not getting a good enough spark.

check the heat range on the plugs, check the wires, and check the dizzy.

but honestly man, good luck trying to find comparable parts for that ZC. i had one a while ago, and i couldn't find a whole lot

 

get a pg7 ecu... i have one i can sell you for 35 shipped... the pr4 is SO rich... i put one on my car for the hell of it and itd barely run.... trust me get a pg7 and youll be like WOW ... your just fouling out plugs and ****

 

ok thx ill try that as soon as i get time.

 

You need to clear up that code 9 before your car will run well. Check your wiring going to the CYP sensor at the front of the head.

You didn't search hard enough. There are plenty of parts available for that motor. Please don't spread biased information around.l

And I would also recommend using a PM6,PG7, or PM7 ECU over a PR4, but an ECU is not the cause of your problems here.

 

i tried a dif distributor that i had lying around but it did the same thing for a moment and then it just died and now my car dosnt even start anymore.

The sensor isn't in the distributor. It's on the front side of the cylinder head and has two wires running to it.

 

and i hope you used a dohc zc distributor and not a d16a6 cuz it wont run.

 

check your m.a.p sensor.
or your dizzy cap and roter.

 

i checked the wiring going to the cyp sensor and everything seems to look fine so im gonna replace it as soon as i get a chance.
