O2 and catalyst monitor not ready
October 18, 2013, 02:58 PM
I bought my car 2weeks ago and I still haven't taken delivery on it because they can't get the o2 or catalyst monitor to read ready!! They replaced all 3 catalytic converters and replaced an aftermarket air intake and still can't get them to be ready to pass inspection!! Wth.. What could be the problem?? Any suggestions?? They want to bring it to a hyundai dealer and flash the computer!! Does that seem right?? Very frustrated at this point!! I just need one code to clear!!
