I have discovered a slight miss fire on my car when i am sat on idle and i rev it to 4,000 is where the miss fire is and when i try to hold it around the 4,000 mark by just tapping the throttle is where the missfire starts.
So i thought i would service it to see if new spark plugs cure the problem however it hasnt stopped the problem.
when i removed the spark plugs there was alot of oil only on the threads of the spark plugs for cylinders 1 and 3 but no oil what so ever down the ports where the ht leads sit, the other two cylinders are dry and look good, i am really confused and dont really know what the problem is so any help what so ever would be very kind
Regards Danny
