OK... give us RPM swing you are seeing at idle. ( in drive and in neutral) I've seen the vibration coming from the hood that was setup by a frequency of the engine. Move the rubber grommets and the vibration went away. Let us know what your RPM swing isLike I sad RPM is not stable,that's why I can feel vibration from engine.Oils are ok.Plugs are changed at 80 000km.Thanks guys for quick reply!
Damn 200k without plug change? I thought I was pushing it at 148k. I too get a hesitation at a stop once in awhile. Might be plugs.I have the same problem. It began when stopping on off ramps from highways. Now it is at most red lights and stop signs. It get worse the longer I drive during the day. The car has over 200k miles. Spark plugs have not been changed.
