I cannot get my 1978 fuel injected spider to idle at all. I followed Wes' instructions for setting the 19mm gap, made sure the throttle bodies were closed, checked timing and still cannot get the thing to idle. The car also backfires when slowing down. The de-cel switch does not have a wire going to it so I know it isn't working. Can anyone tell me how to wire the de-cel switch so I can see if it works. I am open to any and all suggestions to get this thing working correctly. Thanks for any suggestions or recommendations!!
