I hope someone can help me figure out my issue! I have a 2003 svt and have been struggling to fix a rich condition. I have been fouling plugs within 500 miles and I have done many things to try to solve issue, including upgraded coil pack and 8.5mm wires, new O2 sensors, sct itsx standard tune, and i tried finding vacuum leaks but haven't hooked up a Guage yet, so my first (before cat, which is now orp) 02 sensor says im still running rich and i get a bad miss at about 4000rpm. Doesn't always happen but seems to happen more often when its wet or really humid outside. I am only throwing a code for my evap system which is now removed. The lines still run from the engine compartment to the rear of the car but the throttle body whole has been plugged and also the canister was removed. When I look at my engine data I see my long term fuel trim is at almost -6.0. If anyone has an idea please chime in because I'm truly at a loss! Thanks for your time!
