Idles Fine At 1000, But Below This It Bounces Around 500

so ive had my rx7 for 4 months now and its been a great car. ive fixed a lot of issues but my main problem now is the idle. i cannot tell if it is a vacuum leak or something else. it holds great at 1050, and as soon as it hits about 1000 it'll drop to 500 and bounce between 5-700 and can shut off. the other thing i noticed, is when it drops, the turbo goes from 20 vacuum to 5-10 vacuum. any suggestions?

Vacuum leak and/or TPS out of adjustment. Probably a combination of the two.

im gonna go with aaron on saying its a combo of a vac leak and TPS adjustment. the vac leak is probubly bringing the idle down and the the tps is causing the idle to bounce. or you could just have a few vac leaks.

try using carb cleaner to locate a vac leak.
