Sparkplugs! Anything to worry about? Just cured an exhaust leak after installing TSP headers, but when I pulled the plugs they were like this & they have less than 10miles on them! I've put everything back together started the engine and I'm getting multiple missfires on cylinders 4-6-8 (bouncing up to 40-50+ then back to 0), don't know if it was doing that during the leak.
Ticking from exhaust is gone but the idle is really rough when warmed up, only code is po154 and wideband bounces between 14.5-15.
Any suggestions as to what's going? Plugs are NGK TR55

Yep! I pushed all the wires back on, made sure they clicked on & the plugs were snug.
I was getting misfires before just not that bad, so don't know if the symptoms are from driving it the few miles with a leak.
All I did today is re-tighten all the header bolts & check the plugs and wires & started the car up and let it idle till warm, that's when the engine started to shudder & misfires started.
I still have 7 of the old plugs so I might throw them on tomorrow.

All your misfires are on the passenger side of the engine.
probably not coincidence, check your wires again, they can be finicky. (might want to throw a tiny bit of anti-seize on the threads)
Makes sure your coil pack connector is correctly plugged in.
Post up your codes, are they just typical misfire codes or anything else more specific?
Check your O2 sensor on that side, no burnt wires or anything?

I'm not sure what's going on then because those plugs I pulled are from the driver side where I had the leak, so I know everything's back on properly on that side.
I'll recheck the passenger side, but I've only got a code for the rear o2 which the TSP ypipe doesn't use.
Missfires I was just monitoring on an aeroforce gauge so I don't know how acurate it is in relation to misfires but the car doesn't feel happy when it's warmed up.
