Good friend of mine has a bugeye. Stage 2 Cobb OTS. Basically all stock minus STi TMIC grounding mod, exhaust, PPG trans. Stock flywheel and stock pullies. He went to pass someone and at the top of the rpms car shuttered and he got flashing CEL. I told him right off the bat plugs are bad or a failing COIL. He changed all the plugs (trying to find out what type and were they gapped at the moment) and still flickering CEL. So he borrowed some coil packs and found the problem at the drivers rear coil. Fast forward 2 weeks. Now he is throwing CELS P0301, 302, 303, and the AP showed "????" at the end, whatever that means. So apparently ALL cylinders are reporting misfires. Weird. He has mentioned something about a possible faulty o2. So he's gonna change that. Is it possible for a bad front o2 to throw all those CEL's? I've myself never threw misfires for a bad o2....just the general low reading/lean bank CEL.
