    Unhappy losing power

    I have 2004 Vectra with 2.2 DTI and have problem: loosing power, and rpm can't get more then ~2700. Exhaust emission lamp is lightning. If it's happened, then there can help restarting engine only. It's happening more with warm engine.

    I get 2 codes: p0105 and p1105

    Before I changed Air flow meter.

    Now changed MAP (used - I'm not 100% sure about working) and repaired Alternator, but It didn't help.

    I discovered there was bearing ball in MAPs tube, to close tube

    As I said:

    Today I'll recheck the codes.

    if I'm correct MAP is for turbo.

    But why I can't get rpm higher then 2.7-2.9k? I'm driving like on 0.9 diesel motor with one cylinder, without turbo. I can make drag race with school bus - he will win.

    Is it going into limp home mode?? Just wondering if it can be something as simple as o2 sensor or EGR value

    No, this is not showing. Some time ago then Exhaust emission lamp switched off , simetimes showed "Car with a spanner through". But not now.
