Anyone have a isc servo in good condition let me know. Pm me. thanks

Hey guys, spent a ton of time getting everything together and finally started the car after timing chain, BSEK, and turbo rebuild. All of a sudden I didn't have spark. Turns out it was how the last guy messed with the O2 sensor which was causing a short. I started the car and it was running very well, I think proceeded to back out of the driveway pulsing the gas to pull out, then I let off and the car kept climbing in RPM's. I shut it off and made sure everything was okay, then tried to start it

I need an 87 knock box please! Send info to 630-506-9137
