Hi Guys, Went to have a look at this one, relayed to garage. Customer went to restart after short stop, car started but run really lumpy and eventually died and would not restart.Checked fuel pressure and ignition coils all ok Did a code read which showed engine position sensor range/performance. Had new sensor fitted still no start,removed plugs to test for bore wash compression loss, both banks very low, oil down all cylinders brought compression back o/s not as good as n/s!. New plugs fitted car started but made a terrible banging noise which sounded like it was firing back through the inlet manifold. When it was running exhaust on the n/s is smooth but o/s lumpy. . Any Help
