I've already read comments elsewhere about the less than refined sound and feel of the 2.0's idling, but yesterday as i stopped at traffic lights i noticed my entire car was suddenly throbbing whilst idling. Upon stopping, or after pushing the accelerator pedal, the rev counter would drop to 900 as usual but then quickly rise to 950 before settling back to 900 again. The car doesn't feel like it's going to cut-out or stall, and it drives absolutely fine when in actual motion, but there is a definite new vibration throughout the vehicle at standstill, so much so that my gearstick is moving quite a bit, and it sounds like it's been fitted with a diesel engine until i begin to drive off.
I've checked my oil, fuel, temperatures, etc, and they're all as should be. The car is an '05 with just 18k on the clock and has been in for its first oil service just a few months ago.
I've read during an internet search that i could perhaps put higher RON fuel through the car which might help (i currently use regular unleaded, always from the same petrol station) but i'm wondering/worrying if it might be something else more serious, as you do
I've got a third of a tank of fuel left and then i'll give the high RON thing a go i guess but i thought i'd better ask here if anyone else had this kind of problem or know anything about it?
Thanks in advance
Paul
