I am looking for help on what to do with my 92 honda civic cx. My car was running for about thirty min, then it would act like it was about to die, so I changed the main relay and it worked for a couple of days now it is doing the same thing, I think it might be something to do with the igniter but I haven't worked with those much and not sure how to fix them? If anybody has a solution all help and advice would be great!

Run the tests in sections A and B below:

Be sure to perform the K-Test on the ECM. Personally, I would change the Ignition Control Module (ICM) and coil, due to the age of the vehicle. Here's how:

While you have the distributor apart, I would also change the cap and rotor. When you change the spark plugs, only use NGKs.
