As you say it doesn't happen all the time.. meaning its electrical related.. Uhm have you tried unplugging the MAF or lambda and taken the car for a drive to see if there's any difference?

I'm betting its more on the lambda side of things

Its the last thing I thought to do really because both the sensor and MAF were changed just over a year ago. I'll give MAF a clean and see if that helps. Maybe need to look at spark plugs? Been out in her all day and no problems. Passed its MOT today to with flying colours

seeing you passed MOT without any hastles, I'm sure that your lambda is in order :thumbs:

These MAF's are strange temperamental things but maybe just give it a thorough clean and see if there's any improvement in performance? If I were you I'd take the plugs out and give them a good clean, checking the gaps aswell.

Maybe just take your air filter out and give it a good bash against the concrete

I'll check the plugs this weekend. Been out for a real long run today and its been great. Just a little lumpy first thing, despite letting it warm up good n proper. The air filter is a K&N induction kit which was cleaned and oiled about a week ago so I know it aint that

No mate don't oil your air filter It kills your MAF !!

That oil goes into your MAF and just ruins everything in its path.. rather run the filter dry.

Hope this helps bud
