Hi, just wondered if anyone can help, my car has been running lumpy and below power. Engine management light was on. Ran diagnostic on it and it says:

P0420 - Generic - Catalyst Efficiency below threshold (bank 1)
P0202 - Generic - Injector Circuit open - cylinder 2
P0203 - Generic - Injector circuit open - cylinder 3

Any ideas?

Its 2001 1.1 206.

Thanks

Sounds like either:

NGK spark plugs have been fitted.

& / OR

Coil pack has the magic word SAGEM on it.

What He Said

And the CAT, just give the car a blast down the lanes when you've sorted the plugs/pack

thanks for your replies i have put new plugs in and 1 new injector and cleared the codes runs a bit better but not much.
Will check the coil pack in the morning as for the lamda diagnostic said its ok so guess it might be the cat thanks for your help.

NGK play havoc with the misfire detection system, and cause premature failure of the coil pack

Bosch only
