[tony_burrin]

can anyone help me with these fault codes my LCR has popped up with please

p0103-powertrain-Mass or volume Air flow circuit high input

p0172-powertrain-System too rich (bank 1)

p0117-powertrain-engine coolant temperature circuit low input

can anyone tell me what they mean and how to fix them
many thanks

First one will be a MAF fault, either clean it or it'll be broken already, try cleaning it first

Second is a faulty reading from the MAF so see fault 1

Third fault is a faulty coolant temp sensor so I'd be replacing that

agree with above, definitely try to clean the MAF first, with Carb Cleaner spray should not leave a residue on it
