I have a Civic 94 EX (D16Z6), the car was running perfect for almost 4 years, suddenly not start, I found problem with the ignition cables so I replaced it, the car started but when I try to accelerate is like no power at all, I replaced the spark plug (Autolite) the car was running good for about 5 minutes then lost of power like when you disconnect a plug cable and you fell you are driving a car without one spark plug cable, then I replaced the plugs again with NGK ZFR5F-11, same problem it run very good for just 10 minutes, when you try to accelerate from 0 is like one cylinder is not working but you accelerate slowly it sounds very good.
At the beginning while I was trying to find the problem I replaced the fuel filter and I checked the coil and the igniter, look like electrical problem. Any suggestion will be appreciated.

 

As long as the plug wire are on correctly and everything checks out.

I would replace the dizzy with a rebuilt one. We found they last about 150,000 miles then begin to have small problems. We have been through the igniter then a coil which took out the year old igniter. After that we just get a rebuilt dizzy at the first sign of a problem

 

By the sound of things, it's totally stock. Okay, do start with the dizzy. Only use those NGKs in the future!

Let us know if that works!

 

Thanks for your answers, it is hard to believe that the dizzy (distributor?) is the problem, it because the car was running great just before has a ignition wires problem, by the way I also have a Civic 97 (D16Y8), can I replace the Z6 distributor with the Y8? It looks the same, if I can change it I could test igniter, coil, rotor, cap and everything.

 

i dont think that you could use an obdII dizzy on an obdI motor unless you change to obdII. . .

im not sure of this, hopefully someone else can come and correct me.

 

Maybe what you could do is swap the internals in the Y8 into the Z6 dizzy. Not a 100% on whether they're prefect swap or not, but it's worth a look.

 

Nope can't swap OBD1 to OBD2 without more work.

Trust me get a rebuilt dizzy. It will cost less in the long run. I've learned that lesson the hard way.

Others on Turbod16 will back me up on that.

Over time you'll be amazed at what can happen when you do things to your car.

 

Finally I fixed it, problem: the coil, I just replaced it for the one I have in my other Civic 97 (D16Y8) and it works perfect, one of the time I was replacing the plugs I noticed that all plugs smell like gas, so I thought it was because it was not burning the mix well enough, at that time I started thinking in the coil, the spark was not high enough.
Thank for all your answers and suggestions.
