Default Weird idle lately.

So my car sat for about three weeks it’s a turbo 1.6 megasquirt pnp2. Went to start the car the other morning and it started just fine then like 30 seconds in idle jumped to 2300 rpms. It won’t drop till it operating temp Around 185 190 also when I’m driving it and push the clutch in it will jump up in Rpms until it hits that temp. Just wondering what I need to change in tunerstudio. I’ve messed with the enrichment a little last summer when it started getting colder but it never acted up before. Thanks in advance

Tune doesn't just change.

Always start with the basics, it sounds silly.
It make sure you don't have a vacuum leak.

thats what I thought it was at first but I can’t find anything loose or off. My boost gauge reads steady at 25 for vacuum too don’t think it’s a vacuum problem. I’m assuming it has to do with start up idle. Not sure though.

Check your IACV hasn't failed and started leaking.
When the issue starts happening, what is the KPA it shows in tunerstudio under your Manifold Absolute Pressure?

the issue actually hasn’t happened in a couple days now that I’ve been daily driving it again. Not really sure what was going on. Next time it happens I’ll hook up to tunerstudio
