So I recently purchased a 87 T. The guy I got it from gave me a scanmaster with the car that was not hooked up. I eventually got time to hook it up and it doesn't seem to be reading the o2 millivolts correctly, I know the reading fluctuate all over the place during normal cruising but I am having a problem under wot. I'm expecting to see around 800 or so but instead its giving me readings all over the place one wot run will be at 017 the next will be 079 sometimes 600 then back to 005 just wacky random readings. Any ideas? I have it hooked up correctly as per the instructions and at idle all the other reading temp, battery, idle tps all seem to be on target it's just on wot runs no matter if I give it wot out of the hole or gradually increase my speed.
