Default Scans of my 1990 ZR-1

I was getting some advice on my 1990 ZR-1, and the idle stall issue it likes to Have, from Marc Haibeck (Awesome guy to deal with!) and he asked me to pull some scans of how it is running now. I pulled a few sets, and thought I'd share a hot and cold set with you gents. Marc pointed out that the voltage is low and that the voltage for the TPS is also off.

Anyhow, if anyone is interested, here they are:

The App is ALDL Scan Tool running off an android phone. I used the Bluetooth scanner/reader from 1320 electronics.

Www.1320electronics.com

Super easy to use. I just did screen grabs and posted them here.

Wasn't much. Around a hundred bucks if I remember correctly. A heck of a deal for what it does.

Have you tried adjusting the TPS to spec with the engine off?
