Hi folks, new to this. Just bought a07 plate 225 meganesport. Brought it 150 miles up the motorway home, and done another maybe 50 miles afterwards then "check injection" appeared on the dash. Have put 4 brand new genuine coilpacks in and 4 new performance spark plugs in, and still no better. I noticed there is a bolt in the Bank 2 lambda sensor hole, and the lambda sensor looks as if the wires have been cut! Would this affect it and send it into limp mode? Any advice at all would help, cheers
