Have you put a reader on it? Are any faults logged? Looks like the map sensor could be playing up. How does it drive?

yes i have put a code reader on it no codes logged and when the stepper pipe is connected the drives like a bang of p** accelatoring away and then backing off

Have you checked the stepper pipe for blockages has a coil pack failed or spark plug when was the fuel filter last changed could there be a loose plug anywhere? These are the only thing that I could think of

Turn the key to pos 2, then push down and release the accelerator pedal down 5 times, then turn the key back to pos 0 then try and start the car :)

zr 160 & lotus elise have a aluminium 52mm TB

& there is a aluminium 48mm TB which is from some smaller K-series engine I think. Rover 25/45 - MG ZR 1.4 to 1.8 none VVC.
