206 Diagnostic help

[hollypinder]

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?


Thanks

Clear these faults and drive the car. See what comes back.
