    Normally my car hates being cold, so much so that if its been sitting long enough to be starting from cold it lacks power a bit for a few seconds.

    Over the weekend I was installing central locking so I had the battery disconnected for a wee while.

    Since then the power loss is more noticable, to the point of the car jolting for about 10-15 seconds.
    When I pulled out of the estate this morning I put my foot down like I usually do and the car got up to 20mph and just started jolting. It's like the car loses the ability to pick up speed.
    Now the road I pull out on to is quiet a busy road so it could be dangerous to be the random slow car pulling out in front.

    The engine management light has been on for quite some time, but I've had it looked at. Its the ERG valve and a commom problem in Opels. Apparently its bypassed as it's far cheaper to do than replace.
    I'm wondering what could be causing this power loss?

    Hopefully someone knows something.

    I'll post up the error codes when I get home and check them.

    Sorry, post was a copy from another forum.

    Its an 02 1L.

    The ERG valve was done when I got it but I got it fixed. I think it was bypassed, could be blocked off, I forget exactly what they said they did.
    I've still got the engine management light on tho. They said they couldn't remove that as they didn't have the software.

    I'm not aware of any other symptoms. I've had the car for 3.5 months and done about 5200 miles. It's now got 97k odd miles on it. I'm expecting some wear and tear. Engine is in good condition in general tho.

    Ok so I got the fault codes (or so I thought).
    I read then 3 or 4 times and got 0340, 0179 & 9179.
    However I'm now seeing that the first one is the camshaft sensor and the rest don't exist.
    I'll check them again later.

    0179 is a rare one but I have seen it before, it means that the fuel composition sensor is reading an incorrect signal. As far as I know the Agila never had one of these fitted, but I do remember a spate of this issue after Tesco had a silicone problem with their petrol and the cure was to replace the O2 sensors. I will dig a litttle further with this issue.

    Oh thats a relief. I thought I'd gone mad looking at the flashing light.

    I do know there is an issue with my fuel tank. There is a leak near the top of it. I can't get under the car when its doing it and by the time my mechanioc sees it its stopped leaking.
    We're looking into replacing the whole tank, or at least taking it out for a look.

    Might be related to the fault codes?

    I'm guessing I should get the camshaft sensor looked at too?

    Thanks.

    Cam sensor fault codes can be very misleading. More common symptoms with a cam sensor issue is engine dropping into limp mode and getting a RPM hard limit of 4500rpm. But I never rule out anything. What I am going to suggest is find someone with a diagnostic scanning system (Opcom, Elm327) Ask on this forum see if anyone is in reasonable distance. Have the codes reset, have it rechecked and maybe a little live data, then give it a drive, and see if anything happens, will save you time and money just swapping bits and chasing fault codes.
    Good luck and let us know.

    I don't think anyone on here is near me. I live in Ireland, tho I work in derry.

    I'll ask around the local mechanics and see if they know someone who'll help.

    You can buy an ELM327 OBD-II Diagnostic plug in USB to PC Fault code reader from Ebay for £15.00 + P&P
    I also would then download VauxCheck from http://www.enginecheck.co.uk/vauxcheck/ which will cost £30
    Then you can fix anything as you can spend a lot on sensors that have no faults!

    Warning the CAM sensor fault can show up for loades of false reasons!
    If you have central locking and it no longer works it can be the imobiliser which may not show up as a fault code.
    But the ECU will keep saying Cam sensor.

    Hope this helps.
    Regards
    Dave
