i cleaned maf not so long ago, diagnostics bringing up crank sensor as well as knock sensor bank 2 so we put the coils back on back to front so the coils that where on bank 2 are now on bank 1 if you see what i mean. so now its jolting and missing again will try get it back to mates garage to be plugged in again as if it comes up with bank1 knock sensor instead of bank 2 we almost sure it a coil then. but i didnt think crank sensor would cause it to missfire but it would explain the cutting out i get when sat at idle?
