well i have cleaned the whole throttle body isc so it isnt dirt.

it could be a TPS failure. GUZZLER, could you PM me with a price on the 4x4 TPS, if its cheap cheap

SECS has been very helpful in helping me diagnose it, and i have few more tests to try tonight.

at the minute the TPS is reading 0.25v@idle so is working, but something is sending a signal to open the iscv fully? even when warm

will check pin 34 on the ECU to see if it varys? where does the other wire from the iscv terminate? at the tps?

i have been told to bridge the tps at the ECU and then try and start it, should i do this with or without he iscv plugged in?

cheers for all the help and advice guys

thats why i love this forum
