Anyone know wtf this means? Everyonce in a while my tach will jump around like CRAZY, then the car will die. All I have to do it turn it off and on again.

I get a code 15, ignition output signal.

It's started doing this after I got my Alarm/Starter installed, and the turbo. The starter has a wire tapped into the tach signal wire on the dizzy.

Anybody know what this code means? :?:

As I understand it, the ECU is supposed to see power on the white wire from the ignitor unit. It throws a code if that gets interrupted. You could have a loose connector, corroded wire or maybe a failing ignition switch.
