Buying a TII w/ 3800 RPM hesitation.
So I've found this pretty nice '88 TII that I may end up buying. This would be my first RX7, so I just want to ask you guys about it so I know what I'm getting myself in to.
The car seems to be in great shape, except for 2 problems.
It has that whole 3800 RPM hesitation thing. I've read about how to fix this on the FAQ and also done some searches, so I know that this problem is quite fixable. My question is this: I am no mechanic, but I do have some basic skill w/ wiring and electronics. Realistically how much of a headache is it to reground everything to solve this 3800 RPM problem?
The second problem is that it's set to idle at a high RPM because otherwise it will stall out sometimes, particularly when the AC is switched on. From what I know about these cars, it sounds like that could be a problem with the TPS? Is there some other thing that may cause this that I am not thinking about?
Thanks for your help with this.

If it stalls when loads are applied (Like the A/C) your BAC valve is probably faulty. Also a very easy fix.

Or removed, see if the emmissions are still on the car.

BUT you could also just clean up the factory grounds.

Cool. I may end up getting this car then, since it sounds like it wont be too hard to get it running right.
My other question is this: The engine has 110k miles on it... should I get the compression checked on the rotors for such a high mileage engine, or check anything else that I might not normally check?
EDIT: I just read Aaron Cake's FAQ and he says I should check the compression anyway. So my question is how do I check the compression, do I take it to a shop or something? And if so how much would they charge?

buy a cheap tester at auto zone, rip out teh "screw" on the side and the "guts" maker sure it wont hold air. then hook it in one ofr the spark plug holes. you have to un plug someting and have a friend floor it and turn it over and you watch the bounces.
