Ideas please Bad starting

[jade]

Hi all
My rs2 is not behaving well , started having to crank the car alot more to start it and now its got cold she now is very hard to start i have to crank her a lot she fires but takes time to catch then starts on 3 cylinders runs for a moment then catches on all 5 with a lumpy idle .
running very rich , drive a litte runs fine only lumpy idle i run 1.9 boost not problem
car feels strong & quick,but is hard to start & maybe a little flat
problem is not getting better
no codes showing up ??
any ideas please
Thanks Jade

it could be lambda sensor or water temp sensor on the back of the head .

Leaking fuel injectors maybe ?

Check the air temp sensor and water temp sensors - VAGCOM is best for that as it will display information in degrees celsius based on sensor signals.

The ECU needs to know that the car is cold in order to provide correct fuelling for a cold start. Hah - is it that cold in Mallorca right now ?

check your spark plugs

Leaking injectors i think is part of the problem as this morning i poped of the fuel pressure regulator had no pressure behind it, also i will try changing sensors and see what happens . The spark plugs are newish 3500 kms

Well we have snow on the hills here now & thats cold after 45 in the summer !!

Thanks Jade
