Hi can anyone shed some light on these fault codes and if I need to be worried.

p0301 cylinder 1 misfire
c3101
p1301 random misfire cylinder 1
p0255 The ECM detects a discrepancy between the Pulse-Width Modulation (PWM) supplied to the Electronic Fuel Control Actuator (FCA) and the PWM returned from the Electronic Fuel Control Actuator (FCA)
c1555
c1555

All codes read via ob2 bluetooth reader and torque lite.
I cannot find the blank ones and should i worry about the ones I have found?

Non are dated so ive cleared the log to see if any come back.

FN2 type R 07 btw non GT

They could all relate to the same thing, fuelling on that cylinder causing a missfire, perhaps an injector.

As you say if you are not missing at the moment then no clue as to when they are from, clear them and see what comes back is the best way. Then see what comes back.

yeah just have to play the waiting game i guess, I cant say Ive ever noticed it miss so could be a previous fault.
