Alrighty i tryed pulling the codes but to no avail. I was driving trying to get the light to come on and it did. So i drove whith it on for a few minuets to make shure the computer caught it. well i hook up the dignostic jumper thingamajig and i get the CEL to flash. It does a 1...1-2 flash. My service manual says thats a code 12, which tells you the ECM is alive and well. But heres the catch, it keeps just flashing 12, thats all it does. I was just thinking that when i replaced the TB i didnt flip the switch thingy on the back of the instroment pannel (how do you do that anyway?). Could this cause the light to act like this?
