Anyone come across this, started the car after a few weeks, got a flashing CEL, visit workshop, turned ignition off, restarted no cell, drove about 20 miles absolutely no issues, pulled 0300 code, multiple cylinder misfire. Car had new coil packs and plugs last year and has been running really well since. 05, 3.6 C2.
 
Likely to be low volts. I recon OPC got rich with turning off cel. Take it for a good run and put on trickle charge if you don't already do so. Very susceptible to low volts.
 
Good point Montygraphics. Luckily the cel went on its own accord.
