Why have you unplugged it? This engine needs the MAP sensor to calculate the fuel MAP. It's not like the GEN2 with AFM where the sensor only runs the boost gauge and fuel cut protection.I have the map sensor unplugged, thatll cause it right? Also plug wires arent the best, I ordered some but they were wrong. I appreciate the help, it idles and back fires along with intake backfire, I double checked timing but could be off on the dizzy side.
