When I start it will idle at about 1,700 after some driving it drops down to 600 and will stay at that, is the high idle when the engine is cold normal or do I have a vacuum leak?

Normal cold startup. 600rpms sounds a little low. What are you driving?

1900 suzuki sidekick jx 5spd manual 8v, ya it does seem a bit low, I'm gonna adjust it up to 800 do the high idle at cold start is normal?

A higher idle during cold start is normal.

A vacuum leak will NOT cause a steady high rpm, but the idle rises and falls between 1K and 3K rpm's constantly untill the throttle is depressed.

Idle is controlled by the ECM.  So DO NOT try to adjust it with any of the screws on the throttle body.  Sometimes clogged EGR passages will make it idle low.  Sometimes a sensor that isn't sending the correct reading back to the ECM will make it idle low.  So clean the EGR passages and EGR valve and verify all the sensors test good.
When the engine is cold, it will idle higher than normal.  So I see no issue with cold idle speed.

I've been working on other parts of my Sami, not the engine.  Where is the EGR valve located on a FI Sami?  My Check engine light is on and the previous owner said it needed a EGR valve.  I thought I might try to clean it up and see if that will make the light go away.

Mine idles nice and low at start up.  Less than 1k rpms for sure even when its cold.

EGR valve is at the passengers side rear corner of the engine.
Don't just assume the PO knew what he was talking about, when he said the EGR valve needs replaced...read the codes, to determine what code it is throwing and how to troubleshoot it.
Low idle (under 1K) is not normal at cold startup (it is usually in the 1500-2500 range).  I'd say there is something wrong somewhere (maybe the code that is throwing the CEL will tell you where to look.

Woops I adjusted it at the throttle body 0.o I'll put it back to we're it was but with about a half turn of the bolt I got her up too 750 it seems to run better there, i think the PO had turned the idle down because he used the vehicle for hunting so he may have Wanted it to idle quiter, will it hurt anything if I leave it how it is now? Nothin feels different it just idles between 700-800 now instead of 600-700.

If you adjusted the one on the throttle linkage, you should move it back.  Then again, if someone messed with it before, it probably doesn't matter, since you don't know where it was set at from the factory.

Guessing he meant 1990 (not 1900 cuz that would make it a really rare one!)  I think the '89/90's use the screw for base idle adjustment, so he should be fine.

I think you are right on that.  It's been awhile since I've messed with an 89/90, so I don't recall off the top of my head.

Nooe I meant 1900 it's a 2 liter carbed running 14.83 gears haha ya 1990
