i done the sparkplugs this morning and have noticed my engine is running very rich what is likely to be the cause of this?
-
Did you have black or wet plugs then?
Is your engine management light on?
-
Check for codes.
Have look at the air filter, if its blocked change it.
Get some carb cleaner and give the maf sensor a good spraying and then do the breathers ;)

plugs were totally dry done the breathers and cam gaskets when i first bought the car in january 08
they were black tipped no codes atm but now and again it flags up a MAF low voltage code
air filter is a pipercross non oiled panel filter
thanks for the advice ian will try that at the w.e :y

plugs were totally dry......
.....they were black tipped
Sounds more like you're running lean to me.
When you say you have notice it is running rich, were do you feel you're losing power??

Haynes manuals spark plug comparisons myn looks the same as the rich ones
i have only just changed the plugs at 120k last time they were changed was at 80k in 2004 by Inchape Vauxhall Exeter

Spark plugs really don't provide a reliable indication of mixture these days. Since the advent of unleaded fuel the deposits that used to give them their "colour" don't occur.
It's normal for plugs to come out of a modern engine looking black and sooty if it has recently been running cold, or idling for a long period. After high speed / heavy load running they go white and appear totally clean. This is more a symptom of the recent operating temperature of the plug than anything else.
I would say if the engine is running well, and gets up to, and maintains, the correct coolant temperature the likelihood is that nothing is wrong.

Based on the Haynes book of lies........as shown on Champion plugs :-/
If you're that worried about it mate, get a diagnostic probe up the exhaust to check the mix throughout the rev-range ;)
