Started car up this morning and was really juddery and revs were bouncing also! This was at 11am this morning, has been cooler recently but not that cold! Dipped throttle few times and seemed to help it! I then turned engine off and switched ignition back on and all usual lights lit except oil light didnt light but within a few seconds illuminated. The oil light thing appened to me A few weeks ago, but I just put it down to being a bad signal from sensor or something, but seems it could be another problem after this morning episode! My car is a 2008 titanium 1.8 petrol with 42k on the clock but engine has only covered 22k as was replaced at 20k.
