We installed a drag 3 kit on a 00 gsr and the car won't idle now. It will only start and idle if I give it a little gas. It drives fine but as soon as I let me foot off the gas it dies. I've already swapped map sensors, unhooked vaccume lines. I have a very short downpipe on teh car right until I can get another made. Its only like 4" long and neither O2 is hooked up. Does anyone have a suggestion of something to look for or try?

 

neither O2 sensor is hooked up?! are they not hooked up or are they dangling in the breeze?

 

Neither is hooked up?
