dave you are the man ,problem sorted and even the aircon is engaging correctly
stuck a voltmeter between pin 17 and earth,was getting 0.68 volts so i moved the tps until i got 0.3 volts,then pushed to full throttle and was getting 4.55 volts so i,m happy with that
started her up and shes perfect iscv is spot on,and incidently the tps is now sitting exactly half way in its slots
frog i reckon you need to try this out,
