I just droped my zc DOHC , but it stambles in first gear in low RPM. on the take off it sounds like it's going to die ,then you Rev it high , then picks up speed. just replaced plugs , wires and cap. If anybody has any ideas with whats wrong with it let me know ........... thanks .............

 

Maybe a timing problem? Double check it just in case. Otherwise the distributor itself might be faulty.....

bump for other ideas

As he said check the timing both cam and ignition. Also have you replaced your fuel filter?

 

check your codes, then check grounds(by thermostat housing) sounds like a problem i had once too. take off distributor cap and rotor and also the little black dust cap you'll see three tower wires toward the firewall side make sure these are connected and clean. good luck

 

99% of the time on the zc its the dist. it must have just been a bad design from honda i have replaced mine 4 time thank god i got a lifetime warrenty.

 

Are you throwing any codes? Hows your idle? Could be TPS, could be dizzy. Did you have to rewire for MPFI or were u using an Si harness? - Darrell

 

I'm not throwing any codes , I replaced the rotor button , It made alittle diff I took out the Gs ecu and put back my old Si ecu the Ide is alittle bit rought .. I think it's een caused by the headers it's leaking air on the down pipe

what....

 

the dist that i'm using doesnot give you much room to play with advance or retard . I think i'm going to drill that hole alittle bigger so that I could adjust it

thanks for your help PPL shoot me some ideas ,

 

i had that same problem when i did my zc swap. I loosened the three bolts that hold the distributor on and adjusted it, forward and backwards untill the engine ran good at low rpms. Once that was fixed low rpms were great

 

Hey I justed wanted to ask , is that your red crx , really nice is all motor ?I finaly started working on my car , I still have not adjusted the dist yet , did all the work test drove so far so good , you mention that you had the same problem , did it make a big difference ? my does, that when you punch it and at low RMP. let me know

thanks

What parts did you buy for a JDM ZC? Did you just buy a distributor for an 89 Integra?

 

yeah I bought 89 distr , It runs but it's bad in low RPM it completly stumbles , I going to get one from Distr King on ebay .. I also have to convert the plug in ..

thanks

 

i agree with the first responces.. it sounds like a timing problem.
Since it revs up that rules out the ignitor being bad. (usually kills anything above 3k)

If you need a distributor.... I have a friend with a ZC motor that the timing slipped and bent the valves. I think he will consider parting it out and most likely junk the civic.

If you are interested..... let me know

 

definatly sounds like a timing issue when my ignitors went bad it only stumbled at high rpms
