MK3 golf GTI 2.0 8V with running trouble :(

[Sgt Apone]

Its giving me headache and i just want some clues to what it is before i take it too the garage.  Normally when i first run it from cold i suffer from a great loose of power, stutters and if i drop the clutch and rev for 30secs it will either cure it or just make it run better till it clears. dosnt happen every time i start the car either which is weird.  The engine does seem too have leaked a tiny bit of oil but this morning i looked and nothing, its like its playing with me. it does burn oil but not major amounts and when it runs right it runs 100% right. only other thing to add to this is where the belts are on the engine, seems to sound different, you know drive you care forever and you just seem to notice when theres a noise you've not heard before.
Is all this linked or could it be separate problems?? cheers ppl   

 EDIT: Erm on a side note, is there ECU in M reg GTi's and if so where the hell is it lol

Under the rain tray is where you find the ecu

try a new temp sensor for your cold running issues..and take the plastic cover where your wipers are off and the ecu is behind the passenger side wiper

Thanks on the ECU and the temp sensor thing, is that like arm or an arm and a leg?? 

[boneybradley]

temp sensors are about £12 for an intermotor one or £18 for bosch

[Sgt Apone]

ok cheers, ill have a look around tomorrow see what i can see, fingers crossed thats all it is. thanks again.

i have exactly the same trouble, hard starting from cold stuttery power and not instant power when i accelerate.

Someone did mention about the temp sensor but i thought this is to do with the fan for cooling..?

where is the temp sensor located is it the one that sits in the water housing on the right of the engine and has a 90deg angle pipe and sensor sits right here???
many thanks

my guide...it's an 8v but the 16v has the temp sensor in a similar place
