Hello I have a Diesel Sportback and it is playing about something shocking. It is very rough to start up and sometimes needs a bit of revving to stop it stalling. When driving, it attempts to stall so have to save it with a combination of clutch and accelerator work. However, when it gets up to full temp (90 oC) it is a lot, lot, lot better. Have changed the crank sensor and MAF. Any advice?
