It vibrates through the steering wheel at idle and I can feel a slight skip in the ignition timing, like a miss but an irregular one. I checked the sparkplugs and they seem pretty clean, number 1 and 4 were dirtier than the middle two though. I was told the car was serviced by a VW specialist prior to me buying it. Should I replace sparkplugs and leads? Is there anything else I could check before wasting money?
Another issue is a burnt oil smell inside the car, I have a feeling oil is leaking onto the underside of the downpipe... I know there is a little oil leak on the hot side of the motor. Where would this be leaking from?
By the way I consider myself inexperienced when it comes to motor stuff, especially with Volkswagens. I've only ever done oil changes, brakes and the likes. So I ask you in advance to forgive my ignorance hahaha.
