Hello,
New here, glad to be here. I have a 2001 civic w/the 1.7, i have replaced one of the coil packs 3 times in the last 12 months and about to replace it again. wrote it off to a bad coil to start with but now don't think so. Any suggestions? Btw, do have a light on, bad converter, that's it.
Thx for any help.

When the "bad" coil won't spark, does it get both battery voltage and good ground?

Haver you inspect the spark plug?

 

Using OEM ignition coils?
Using OEM NGK spark plugs? When were they last replaced?
Check wiring to this coil.
Check your grounds too.

 

Thx
Yes all oem and plug/all plugs have been changed (can’t remember brand).
just had a respected mechanic check it for me, he couldn’t find anything either. Even took it apart to make sure the timing belt was not off, it was good. He adjusted the valves, replaced all the coils, plugs again and put it back together. Been running good so far, time will tell??
