  1. I was starting to feel really good about having just saved a $400 labor bill by replacing a new coolant reservoir and thermostat myself - only to discover a bad misfire upon restart. Computer codes P0300 (random misfire), P0306, P0304, P0305, P1319, P1313, P1318, and P1314 all misfire codes for cyl 4,5 & 6. The only thing that I can think of was that I had to disconnect the fuel lines to replace the reservoir. Coil wires appear to be intact. Any ideas about what I could have screwed up? I didn't knowingly disconnect anything else but not that familiar yet with the 996 ignition system. Appreciate any leads.

    Your coils are cracked, you spilled some water/coolant over when refilling, and this is probably the case. I replaced all 6 coils and plugs and the codes cleared.
