This is a weird one but here's the symptoms;
Starts spot on perfect from cold every time
After I've driven the car for a decent amount of time and the engine is running at optimum temperature it doesn't like starting once turned off. It turns over and sparks as normal but takes a while to fire up.
Another thing I've noticed more recently is once I start the car it revs up to about 1800 by itself and then settles to 1000 before it gets warm and then idles at 800 as it should.
Also once the car is at optimum temperature when I come to a stop EG traffic lights the engine idles at 1200 instead of 800.
the car is running rich as hell too, all my mates think the smells great my my wallet is starting to disagree.
The timing is set up perfect thanks to *RubJonny*
The car is running magnecor ignition leads
Plugs all recently changed
Brand new coolant temperature sensor 3 days ago (genuine Vw part)
Coil pack, dizzy cap and rotor arm less than a year old as well
I cleaned out the intake pipe and throttle body with a can of wynns carb cleaner but it made no difference.
The car does have some halfords special max power cheap nasty induction filter that came with the car but I borrowed my mates airbox off his GTI to test if the induction filter was the issue but it made no difference so i ruled it out.
Any help would be much appreciated as 260 miles to a tank is stupid
