Good morning, after my success at finding and curing the problem with my ABS issue for the MOT, i'm going to cure another long standing niggle......

Iscv not working.... it used to be up and down, then it just stopped doing anything.

When I unplug when cold it does nothing, idles at what I've set it.
When I unplug when hot and its been for a run out, nothing, but engine revs higher on its own at about 1100-1200 rpm and I think it sounds a little lumpy too tbh.

Had iscv out and cleaned, it is moving freely and pulling in and out when 12v applied across terminals,so this is telling me possibly something else, like its not being told what to do, so I've ordered an air & a water sensor from msd, due to never replacing so far and hoping its one of these that's gone faulty and also effecting the idle when hot.

any thoughts from anyone who has had these type of problems previous ?

thanks

Gary.

With the ignition on, have you got 12V on one of the connector terminals?

Have you checked for continuity between the second terminal and the ECU terminal 34?

Also, check your TPS setting:
(for a PF09)
1. With the ECU multi-plug plugged into the ECU, turn on the ignition.
2. Connect your negative probe to ECU Pin 1
3. Connect your positive probe to ECU Pin 17
4. Adjust the sensor to read <0.35volts at idle position.

If TPS setting is OK, may be worth trying a different TPS if you've got a spare.
