Idle problems with vems

[nip]

Evening all it started a few weeks ago it's started to rev at about 1000-1150, I've pressure tested the bottom of turbo back to the inlet no leaks what so ever all vacume lines tested , I've changed the isv air temp Sensor even the water sender on the back of the head .
Tonight I changed the Tps and it started to rev at 1400-1500 rpm I've logged it on vems idle should be at 850 but for some reason it's too high any ideas would be much appreciated

without the log its difficult to guess...

have you calibrated the TPS after installed the new one?
have you downloaded the patch files for CLT and IAT sensor?
send us some logs and we can see what's wrong with the configs or Hardware problems.

I can send the log if you like, I have shown a few people and they say the logs are ok nothing to show the problem

I would check the ISV is moving freely, and that you car feel it working, vibrating double check I know you said you replaced it but worth a look


If you do not post a log cannot help much, need to have a look at your config

[popdemonic]

yeah the isv is occasionally stuck open or some dirt caused the valve couldn't be responded or moved freely.
i would tried to spray or soaked it with carb cleaner.

If you hold it you can feel it vibrating when the engine is running, that will show its working

you can look for airleaks with some spray brake cleaner or try ignition based idle control in vems.
