    confused REALLY werid power output (2.0 DTi)

    heya,

    okay this is really odd i work all week and dont drive the car till the weekend and one friday it dident start. RAC out and supprise supprise it started first time. revved it a bit and it was okay. its fine now he recons it was a stuck EGR valve.

    But now a new not problem its just weird. when i first start it the car has no power untill 2200 RPM then oh my god it ripps your neck muscles off. also the noise of the engine becomes alot louder all of a sudden. only happens a couple of times then after starting then its fine steady power from the bottom to the top as normal.

    any ideas what might be stuck somewhere?

    Will

    A good place to start would be remove the inlet elbow & clean it out, clean the boost sensor which is attached to the elbow while you are at it.
    It's a real messy job but worth it, you could also go down the route of taking the egr out & de coking that too.

    Mine used to do that (Astra 2.0DTi). There'd be nothing, nothing, nothing, then it'd pull like hell spinning the tyres in the dry, leaving a huge plume of pure black smoke.

    Mine only did it once in a while, usually when warming up on a cold day. Never did figure out what did it, as it only did it once every few months.
