This is important info, and also the reason I don't run a coil cover.

I immediately locate the bad pack by unplugging the INJECTORS one at a time. Once located, LEAVE the injector unplugged.

I then limped the car to auto zone safely on 3 cylinders with a flashing CEL.

Asked for a 2003 coilpack, said he could order it.
Asked for a 2004 coilpack, he said it won't make a difference, but it did. In stock

Fit lots of Honda models and most S2000s. Made in Canada. The Delphi name seems reputable and cool. I know... Denso can do no wrong, of course, and Delphi is not any cheaper. But wish to hear opinions on an alternative coil packs other than Denso.

Service limit is 1.3mm on plug gaps. You would not need to get a new tune, and oem plugs should not be re-gapped, just replace them when necessary.
