    can you do the flash test on it? sounds like the airmass meter to me tho for a random guess.

    Depending on how old the car is you may be able to read the fault codes and see why the car is having problems.

    Have a look at Topbuzz Web Site - News & articles on Vauxhall / Opel / Bedford / Holden motors @ www.topbuzz.co.uk - if you're lucky you can do the paperclip test which flashes the faults up on the dashboard.

    Whats the problem with reading the codes off ? If its a 1996 ECU then you should be able to short out the appropriate wires and do the flash test as posted above.

    If you find out why the ECU is complaining it should lead you to what you need to fix.

    even if it is newer it'd be worth your while taking it to a garage with an obd reader, rather than randomly changing sensors.

    Re: corsa accelerating slow

    My 2000 1.2 16v corsa was doing this, I had it plugged in at my local garage and it was the EGR valve.

    I sold the 1.2 engine on here (stated needs EGR valve changing) as I put a C20XE in my corsa and he changed the EGR valve then it ran fine

    Re: corsa accelerating slow

    As it's an intermittent fault, and the car's been modified, I'd also be going over all the electrical connections and checking for damaged wiring.

    I had this problem with my Astra last year and it was the coil pack. Bought a new one and swapped it over and I never had the fault again.

    Yup. Almost any fault will stuff up your engine management and it quite often goes into limp mode. You might want to check all engine earths.

    if the eml light comes on follow the link further up this page, it tells you how to read the codes with a paperclip if you don't have access to a proper code reader
