    Hi, my car is behaving strangely and I have no idea what’s causing it after hours of research, the revs keep dropping very slowly and sometimes sticking at around 1500 when I’m going slowly. They won’t change until I release the clutch again and put it in gear. I also have the fault code p0171 stored. It seems to be fine when I’m stationary, and when I’m going faster than around 20. If anyone has any ideas I’d really appreciate it. Thanks

    Seems the fault is related to a split pipe, too much air going in from the split pipe. You might have a small leak somewhere, either that or a faulty sensor.
