Help (see Pics)

[gt-ahhh!]

hello

today i finally got around to taking my baby down for a dyno sess, hoping to have a wank over the printoff. but instead, it chose the perfect time to develop a bad misfire around 5000rpm. i know there are loads of topics about this, and ive read plenty already. but none of the pics seem to work, so i cant quite figure out what my problem is.

i feel it is probably the coils, i just took them out and they all have what appear to be burn marks on them...

ive read that people with cracks etc have painted their coilpacks, with nail polish of all things, and proper electrical sealant sorta stuff, and this has solved the problem.

other than that im pretty stumped, maybe plugs, or something to do with the ecu since its still stock, but running a/m turbz and 16psi. i find it odd that it happened all of a sudden when previously its been running fine.

any help appreciated!

cheers,

mitch

btw, got 168rwkw at 5250rpm. curve is heading skyward still...

hoping for 230 at 6500rpm.

Looks like your coil packs are pretty farked. Your better off just saving and buying some splitfires. I had the same problem and tried many things to fix it but in the end they were past their used buy date so just ended up buying new ones.

thanks for input, i agree they look shoddy. shame, i just sold my spare set a few weeks ago!

ANY MORE OPINIONS!?

looks like coilpacks to me.

but other causes of misfire can be a failing cam angle sensor, or a failing ignitor module. can also be injector related.
