My MIL Eliminators ( from Dallas Mustang ) were reinstalled on my car after my trans was replaced. They are on securely, but my check engine light comes on and off, before the trans was redone I never had this problem. I did notice they hung the cables leading to the MIL's around something, but I can't get far enough under the car to see. Also I hooked up a diagoistic tester to the computer and it said Bank 2 O2 sensor. Has anyone else ever experianced this problem ?
