That's O2 sensor heater circuit malfunction on all the sensors. Can some one please give my a logical explanation on what could cause the problem on all four sensors. 1998 Silver Frost CSVT #4014 Some mods My car

But you convinced me to check it a gain and what do you know there was crap on the blade causing a bad circuit which I couldn't tell with the tester because I didn't pull it out.
