I'm hoping someone will be able to tell me as to why my car on ocassions will stall when you put it into reverse when cold, or when sat idleling the engine tends to grumble unless you hold the revs around 1000rpm for a couple of minutes? Just recently I've started to hear a ticking noise coming from the throttle. ( I assume it's the throttle as when you take your foot off of the accelorater peddle the ticking noise stops after a couple of seconds then starts again when you put your foot on the accelorater again.) I'm unsure if this is linked to the above mentioned, but I took the car upto the Lake District over the weekend, and although she ran well going up and whilst visiting family, coming home yesterday whilst on the A1 I had been doing 75mph for about 40 minutes and had to back off to let a truck to come into my lane. when I backed off I got a sudden cloud of blue smoke coming from the rear of the car. This is the first time this has happened since I got the car in March.
Although the previous owner had the car serviced before I bought the car off of him. I've noticed that the fuel pump's making a loud humming noise coming from it. Would it be best to replace it? :confused:
I'll try and upload a video of the ticking and other noises just to clarify what I mean asap.

I would check that the OVP relay is all good for the engine idle, the smoke will be burnt oil from valves and nothing to do with it, it should isle at around 700 I think
