Hi All, Dropped off at my place last night, cutting out when revved hard. Had a look this afternoon, 1 P1521 clutch switch. 2 P1112 fuel rail pressure. Clutch switch found stuffed away under dash, so refitted and connections cleaned. Checked fuel pump in tank, 3 piston sensor, rail pressure at 2500rpm was varying from 230 to 750+ bar. 300 bar at idle. When revved would rise rapidly then drop out, same reading at ECU, so suspect rail sensor. Was willing to check deeper till I found it was running on RED!! I don't want to get involved with cars people cannot even put the right fuel in. Would anyone else have done the same thing?
