I know it has to do with the oxygen sensors but what???   Tbow (Tbow) Member Username: Tbow Post Number: 99 Registered: 12-2002 Posted on Monday, March 24, 2003 - 11:21 pm:    I had the 1187 before and it turned out one of the O2 sensor got diconnected. How old are the sensors? If you got more than 80K miles, I would say new 02 sensors. It looks like your upstream (before the cat) and downstream (after the cat) are bad.   Bill Howell (Billh13) New Member Username: Billh13 Post Number: 4 Registered: 03-2003 Posted on Tuesday, March 25, 2003 - 09:04 am:    Where do I plug in to get the codes and where do I buy a code reader?   gordon sitts (Gsitts) Member Username: Gsitts Post Number: 71 Registered: 10-2002 Posted on Tuesday, March 25, 2003 - 11:57 am:    Bill I got my code reader thru Advanced auto parts,It's an Actron mod cp9135 and cost $135.00 It plugs into a conector on the kick panel under the steering wheel.You use this one by plugging it in and turning the key to start but not starting the engine. It links up and reads the codes in english except manufacturers codes which are by number and can erase them based on what you do with the control buttons   Reed Cotton (Reedcotton) Member Username: Reedcotton Post Number: 54 Registered: 01-2003 Posted on Tuesday, March 25, 2003 - 12:23 pm:    If you have a laptop, try http://www.OBD-2.com.
