I gave my car a service a few weeks ago which comprised of oil, filters and spark plugs. The plugs were NGK items and the gap was not adjusted as it appeared to be near enough correct (had the Haynes out, but can't remember the setting it said).
Since the service the car has a very slight rattle from the engine, I think this is what could be commonly desribed as pinking, but I'm not entirely sure. I ran half a tank of V-Power last week to see if any deposits were causing problems, but the noise remains.
I suspect the gaps on the spark plugs aren't correct, but I don't have any knowledge of what adjusting the gap does, the best way of doing it, or whether it's causing the rattle. The oil used was 10w40 Semi synthetic, which I have used since purchase with regular changes, so can't see this being at fault.
Any ideas?
