Idle at 1400

Hello.
Looking for someone that I can meet up with the help me diagnose why my car idles at 1400. I want it down around 750-800rpm.

Its a 1987 Toyota Supra Turbo. Has a HKS piggy back ECU and a boost controller whether that matters or not.

I am just not sure whats going on here. At one point it would start out at 800 but when it warmed up, it would idle to 1000.

The other day I went to coffee and cars and when I went to leave it was pulsating from 1400 to 2000. I finally stopped and shut it off then when I restarted it later, it was fine but now its at 1400 RPM.

I am not knowledgeable with fuel, air or vacuum stuff and am seeking someone that can help me get this running right for some cash if you want.

Chris
