Idle problem 1988 Supra non turbo

Well...I will tell you the same I tell all my 'car-buying' customers and friends.....take it to a trusted mechanic that is experienced, and have him check the whole car over. Have them do a diagnosis to see whats wrong with the idle.
The car lot selling it should be willing to pay to have it diagnosed, but most are just greedy, and want your $$$.

You see, I was a new & used car salesman for 3 years, so I know their ways.

Either they already know what's wrong with the car, but don't want to spend the $$$ to fix it (cause the cars not worth putting any 'serious' $$$ into), and they don't want to loose $$$ on it. Or what???

I would be VERY careful with that car purchase.
