316 running problems still not sorted

[rwdrevell]

my 316i compact is still not running right, after its third running symptoms has cropped up. i have just replaced the throttle position sensor on it and its still hunting whilst foot is dead still on throttle. the revs go up atleast 2000rpm then back to normal where it should be to where the pedal is. if you unplug the throttle position sensor, it runs, but fades abit around 3-4 thousand revs then pulls through and goes fine.

CAN ANYBODY HELP ME???????
