Well the only way it'l run is with the pipe off wont with it on unless i unplug the air temp sensor then as soon as u rev it splutters like fuck then dies!!

With the pipe off it smokes, think he tried the regulator but obviously could be a prob.

Even when its warm it still does it so not sure if its the ISCV as it still does it when u unplug it but thats 1 thing i havnt changed.

Think its more likely 2 be a sensor now i think about it as it did slowly get worse and run badly till it stopped but that was about a year ago now

Will check the TPS valves cheers mate
