Sadly have had no joy, it went into a local garage last week, plugged into the diagnostic machine, no fault codes at all, throttle body was cleaned and tested all ok, plugs were fine, sadly couldn't afford to leave it with him cos the bill was clocking up with every hour he spent on it. I have noticed however that it gets noticeabley worse the less fuel i have in. with a fresh 20 quid in, its fine for about 30 miles then just gets worse to the point where when im due to fill up again i can barely get the car off the drive!!! and since this problem the consumption is dreadful, im beginning to think that it may be a fuel pump or fuel filter problem?????!!!!! let me know how you get on, GOOD LUCK!!!
