   As the title says. I have it running better with different injectors and it was revving fine etc then i went to drive down the road and the engine just revved like the clutch had gone and now it wont rev, you have to hold the trottle open to get it to start and it just chug and as soon as you let the throttle go it dies??????????

   You sound like you're in a big rush lol.
   
   As for the Engine, Are you running a VTS ECU now?
   
   Is the Engine light on?

   Problemo solved! i took the line in off the fuel pump and blocked it and put the fuel return into the pump but had a play yesterday and realised the pipe i blocked is also a return pipe from the filter so it was pressuring up to much causing the over fueling, i have now put a T peice in so they both go back into the pump and it runs fine!! Now i know what people mean by dual fuel return!!!!

    Could be anything. Sounds like the ECU is looking for a sensor signal and not getting it so either a sensor is faulty or not plugged in e.g. MAP or crank. Lambda is less likely as it doesn't read from it when the engine is cold
