4th Pistons misfiring

According to my COBB Accessport my 4th pistons has been misfiring as well as rich fuel mixture. The car runs smooth, screams like a crazy banshee when WOOT and idles fine. But I have been noticing my air/fuel gauge has been going crazy at times but usually stabilizes quickly, its that normal? I am lost as to what is causing this. I do have lighter flywheel, coils, and bigger fuel injectors. Thanks

Sounds like you might have a small boost leak.

I think that might be it. I have been noticing my boost has been spiking up and down erratically since the misfiring began. My current map is pushing 20psi but my boost has been jumping between 15-20psi like crazy. As to Lenny question, I haven't notice any oil burning since my last oil changed.

Okay good. :tup: Maybe we should forgo the WOT run until we have a look at the normal driving log first though.
