rebuilt engine, and yes, all timing is correct. replaced ISCA sensor because that's what I was told problem was. didn't solve the issue. The hoses are good, and all connections are tight. Please give me some direction.

The first thing I would do is run the codes. Here is a guide to help. Also, disconnect the throttle cable from the throttle body, it might be holding the throttle open.

I would check the EVAP purge solenoid, once removed you should not be able to blow through it.

Basic Idle rpm (After warm up)

A/C OFF .................... 700 ± 100 rpm
A/C ON .................... 750 ± 100 rpm

Here is the location of the valve so you can check it out. Check out the images (below). Please upload pictures or videos in your response of the problem so we can see what's going on.
