I'll try the stethoscope. Also going to double check pressure while driving, even though my wideband tells me it's getting enough fuel.

Thanks for the offer Tim, but i'm running FIC 1000's with EV6 connectors. I have a set of TBSS injectors I can put in it.

Your wideband is showing the air ratio, not the fuel content. A cylinder not firing can actually show lean on your gauge since the there is more oxygen in the unburned air and fuel.

Well, started checking some things tonight. Was going to just swap #7 injector with number 5, but the little plastic nose fell off into the head. So I had to yank the intake. Figured while it was apart i would ditch all the plastic pieces and lube up the o-rings. And since I had all the injectors out, I hit them with a few shots of brake cleaner.

Get it back together and what do you know, it's running great! I'm actually surprised that cleaning the injectors with brake cleaner fixed it. I will still contact FIC to see about having them cleaned.
