Yes. 1.6s have a second coolant based valve on the side of the intake manifold, so tune the bypass valve until it’s livable when cold and hot, and if I recall correctly, it’s not the worst idle once you’re done.

I blanked the isv on my '91 1.6L car.
also removed the 'thermo-valve' from the inlet manifold & made a blanking-plate...
first ~min after cold start needed some throttle-pedal covering but after that idle was stable[img]data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7[/img].
gone with itb' so had to use old photos.

Revisting this issue with an update.
Got a replacement Idle speed control valve ( the one below throttle body) and it made no real difference. Pissing about in settings on the Speeduino, under idle control I changed the Idle Valve Direction to reversed. And this seems to have solved the issue!
