scangauge showing misfires?

[IntimidatorSS]

so with my ngk tr55's my scangauge was showing 2-6 misfires but the car is running fine no sputtering or nothing like that but I am getting up to 4 degrees knock...switched over to ngk tr6's same problem..anybody have an idea what it could be? maybe try autolite 605s?

I think Scangauge is a big piece of ***. In my 01 GTX, with no mods, i have 35 degrees of knock retard. WTF. And in my GP 08 completely stock , i have 25 of KR. I dont trust anything now with that gauge.

Yea I honestly dont know how I could be showing any misfires with 2 different sets of plugs but the yet the car runs fine

I think Ill try out AL605s gapped at .55 and see if that changes anything

Most likely it's not the gauge.

My gauge would show misfires at idle, but they were barely noticeable and very minor. It was confirmed by a professional scan tool, it got the same reading.


As for the knock, do you experience that at idle?

yea I would get like 2 misfires at idle when id rev it up then they'd go away..no knock at idle
