Hi all, me again.... Elvis has developed another problem :-( when i'm stopped at a junction or lights when the engine is warm the revs dip below 1k, i think about 700 to 800. Not sure if its just my copen or not but when i first switch on the revs sit at about 2k then gradually drop to just above 1k. Ive had it to the garage and they found oil in the spark plugs but told me theyve resolved it by sealing (dont quote me gere) the spark plug tubes. 1 oil leak and fix later, im still seeing the problem. Anything youve seen before?
