Hey everyone. Well I am a newb to the RX7 world. Just picked up a 87 GLU last friday. The idle however sits at 1500rpm. When u start it it jumps to 3k like it should and then falls to 1500rpm. The adjuster on the throttle body is all the way in so I cant make it go any lower. The temp also doesnt even go 1/2 the whole time i have drove it. I restet the ecu and it drops down to 1000rpms but jumps back up shortly. Do you guys have any ideas?

I already plan to do a full tune up so I wont have any problems passing emssions(i hope)

I have a video but it is at home.
