    Hi there, I have been experiencing the same problem with my car for a couple of months now, with the check engine light coming and going intermittently, with it staying around longer, and coming back sooner after I clear the codes on my reader.

    The problems I've been experiencing -

    1) Excess fuel usage.
    2) Car surging whilst idle (When stopping and starting in traffic car will stick to 2000 revs when out of gear for a few seconds)
    3) Loss of power whilst accelerating.

    I have read some solutions online with people recommending to replace the Purge control valve and the Lambda sensors, but I would like to receive some further guidance to pinpoint the issue further to make sure I get it right.

    Any replies will be appreciated!

    With engine idling take off oil filler cap does it make a difference if it does it could be the breather diaphragm in cover split.
    Can always take purge valve off and try and blow through it if you can then it is naff.
    Lambda sensors are probably just flagging the problem via the fuel trim readings.

    Yes, good luck indeed. Old Salt's link left my head spinning with all the different 'solutions'. Never knew these cars were so problematic.
