Thanks for all help and suggestions I'll check them all. I'm wondering if it's worth buying a fuel pressure gauge or getting the fuel injection specialist to check it for me if they are really expensive. Sure does seem to be super thirsty for only a 1.8 litre engine it seems to use £10 of unleaded just backing out the garage a few times. Sure I read in nissan press release they could do 45 mpg at 56 MPH ..i would be happy with just 30 when i'm just commuting to work
I took a plug out tonight and sparked it of another running engine and result was no spark.. after cleaning again it worked perfect so i guess plug fouling is my problem but why it fouls up so badly is a mystery
. Hope it clears up when I get it back on the road... maybe the rings just need bedding in to stop it oiling the plugs up
