    Can you help with these error codes?

    Sorry for the new thread, I have a new problem. History can be seen in the 'no revs' thread.

    It was struggling when in idle, which I guess was to be expected after sitting so so long. I took it out for a drive, seemed to be going okay, but then I would lose power and the ABS light and Warning light came on the dash. This happened 3 or 4 times, but restarting the engine immediately rectified the issue. So got home and checked for errors codes, the found the following:

    (I think these descriptions are correct)

    P201a - Misfire of Cylinder/ Reductant Injection Valve Circuit Range/Performance Bank 2 Unit 1
    P201d - Misfire Harmful to Cat?
    P201e - Catalytic Convertor Effiency?
    P205f - Reductant System Performance?
    P2044 - Reductant Temperature Sensor Circuit Low Input
    P2046 - Reductant Temperature Sensor Circuit Intermittent

    Does anyone have any advice from here?

    Misfire & smart never a good sign.
    Could be a dodgy ht lead or coil pack.
    Hopefully its not an engine in need of rebuild.

    Has it been using any oil?

    ABS light coming on and lack of power until restart can also be a cracked reluctor ring. Fingers crossed it's something simple and cheaper like that as an engine rebuild is never good news.

    Have you tried putting a tank full of injector / CAT cleaner through it? Reluctance to start / idle after a long period of sitting still might be down to a partially seized alternator.
