Nah this has been happening since i got the car and the aircon is switched off, i'll check those plugs to see if its goes off with one of them out. id say they werent going full pelt but a bit of a speed. Thanks for the replys will check now and post back with findings... P.S Nervous if it is to mask a cooling problem as i was worried that the owner i bought it off only had it for like 4 months anyway of checking to be clear that its not got cooling issues?
