hey guys, my car hasnt been running right. i have a a stumble/misfire. i just did a longtube install and the car ran great for about a week then started misfiring. i used fastbirds heated 02 harness and bosch 02s. i thought it might be the02s so i replaced them under warranty and the problem didnt go away. i changed the water temp sensor in the pump with no luck. all plugs and wires look good. so i bought a moates ALDL cable and did a scan with datamaster. my left side BPW ms is always yellow and the LTerm, STerm counts go lean when it misfires. is there a way i can share the file and someone help me diagnose the problem? i still havent had the egr tuned out could that be causing the issue?
