Thanks for the suggestions... I'll try cleaning the injectors and ICV. It seems as if there is a slight misfire at idle when i'm running on petrol, so that could be the cause.
I've already tried the relay from my parts car (which started and ran fine) to no avail.
I just had my Inspection (passed fine BTW!) and the CO level was very low, onlt 0.12% when i'm allowed up to 4.5%. The examiner said that my mixture appears very lean, so maybe my fuel pump or filter could be clogged too, causing a lean mixture and hard starting.
I've taken the pump off my parts car, and ordered a new filter, so I can change those just in case.

Kind Regards
