Hi all,

getting rough idle and misfires after driving for 30-45 minutes, worse when restarting after shutting off for a bit. Getting codes 29CC, 29CE, 29DO, 2AAF. Just changed ignition coils and spark plugs as first step with no change.

Datalog of idle: https://datazap.me/u/lukeacjm/idle?log=0&data=3-19

Datalog of small run (didn't want to push the car): https://datazap.me/u/lukeacjm/run?log=0&data=3-4-19

Looking at AFRs for bank 1 and 2 I am guessing it is an injector on bank 1? Spark plug on cylinder 1 smelt of fuel

Thanks,

Luke
