Could someone with a 93 Cobra, or someone who knows for sure help me out here? I'm just finishing up putting back together the entire engine and wiring on a 93 Cobra that I traded for and have only one vaccum issue that I can't figure out. I'm pretty sure the vaccum size line plug on the MAP Sensor is just a vent hole from what I've read. Is this correct? Also, I'm missing one vaccum line on the Vaccum Tree, or should I say, I have "no idea" what plugs into this smaller line on the Vaccum Tree. If you plug it off completely, the engine will die. Like I said, when I received this Cobra the engine bay was basically stripped, but I have it back to original except for this one issue. Can someone tell me where all the Vaccum Lines that plug into the tree on a 93 Cobra are supposed to go? I appreciate any help...
