thanks for info , no joy afraid list what I have found
pins 1and 2 on ecu to earth 10.9 volts , resistance on iacv both after market and genuine on 20 ohms scale 0.03 , voltage from iacv pin 2 to earth 12.4 v.
other things that I have found when reved pin 2 voltage on iacv connector goes up to 14 v (alternator voltage ) ?
when it does idle , switch lights on and dies'
used mates solus scanner if tps set at .5v idle switch switches off , adjust to .2v and idle switches on ,
let car idle for 5 min switch off , start up again , goes to pot.
