    Thought it wise to start a new thread on this one now. My '99 Astra G 1.6 16v (I think it's the Z16XE?) is holding back - idles OK, but under load does not like going above 2000 RPM. The garage have checked all the sensors they can get readings for, tried a replacement fuel pump and are trying a compression test later on today. Any idea what the problem can be? I'm really starting to panic now and don't know what the hell the problem can be - the garage are stumped too. The problem only started on Friday night, but has got progressively worse. Car smells like it's running rich, but just won't go!

    There's a bit more info in my previous thread: http://www.vauxhallownersnetwork.co.uk/showthread.php?t=172376

    Thanks chap - I believe they've tried a replacement on there today - no joy. I'm beginning to think it's a worst case scenario - but don't want to shell out on ECU replacement if it's not needed. Help still very much welcomed!

    If it's a '99 Astra, it'll be the X16XEL engine - the Z16XE wasn't used until the 2001 model year, ie Sept 2000 onwards.

    Would that have meant that fault codes 170 and 309 might have different meanings to the "fuel trim low" and "misfire" that I have been given?

    Sorry to keep on guys, but I'm at my wits' end and really don't know where to go next. We've only had the car a year and seem to just keep throwing money at it.

    If the garage you used didn't know which engine was fitted then I'd doubt their abilities in general.

    Sorry guys - my mistake on the engine type, not the garages. Still having problems though - seems to be worse when engine is hot and/or when trying to drive up hill.

    I had a similar problem...it was the coil pack on mine, but I see that you've tried that already. Have you tried cleaning the EGR valve and throttle body?

    Idle control, Air flow sensor. Could be a number of things. I would suggest going to a vauxhall main dealer and get a proper diagnostics done. not cheap but worth it in the long run. Could save you a fortune. But get the work done in a local competent garage it will be cheaper.
