Driving the other day, the service engine light started flashing and my disco 2 began running very rough. The car is very shaky and not much torque. At idle the service engine light doesn't flash, but any pressure on pedal the light begins flashing. Car is VERY shaky. Almost feels like it's not getting enough fuel. I put a code reader on and was getting 02 sensor, cycling 8 misfire, cylinder 4 misfire and p1300 and p1590. I had all plugs and wires replaced at foreign vehicle service center hoping that would take care of it, but no luck. Put code reader on tonight and getting same 5 codes, except cylinder 1 misfire instead of cylinder 4.

Anyone have any experience with this?

Thanks,
