Misfire on cyl # 8

[cmt_cibarra]

I have posted my stock tune and my current tune
as well my logs for the misfire on cyl # 8


I have switched out the coil with a known good one.. number cyl # 6

Cleaned the plugs, switched the spark plug...

What's my next step..

as long as you are running in open lope u should be burning the spark plug ,, but if you have changed the spark plugs and you still have missfire
mmmmmmm
coil checked ,, try to check the injectors Wiring

Check the coil and then check the ignintion module,, basically switch the whole coil pack to the other side...now what I just finished was switch out the injector of number 8 to number 3 i think... lets see what I find...

Thanks for your input... vette_c6

Okay problem sloved... i'm using the spark plug that has a built in resisitor to provide more spark... well one went bad... now going to the parts store (fav. part) to get some NGK ultras... let see how they work...

[vette_c6]

what was your spark brand ? part number ?
and whats mods are in your car ?

[cmt_cibarra]

LG long tube headers, ported TB, cold air intake, pulley, borla exhaust...

Pulstar spark plugs, http://www.pulstar.com/

by the way the NGK.. was a downgrade from the pulstar.. and yes I did look for knock, and adjusted as needed..
