right lads here's one:

my S1 never overheated or got hot when started.

couple months back she started dropping her revs when slowling down at junctions and cutting out.

was told air leak so i changed:

hoses
manifold gasket
inlet gasket.

still cut out so was told by a tuner it was the fuel pump.
I have now changed that today.

NOW HERE'S THE PROBLEM
started her with the new pump. And it starts overheating within 5 minutes and the fan kicks in, she still drops the revs and dies


seriously if i cant sort it then i'll sell her to the breakers because i paid £3k and only had 2 months drive from it.
since May it started cutting out and now ive had it.

can anyone shed any light on why its started overheating and still dropping the revs??
