  1. Both Low beams are out - Hi beams work fine. Are they seperate bulbs? Thanks. 1st time posting.
  2. Hopefully I can now close the chapter on this one. I appreciate everyone's input on this board. Well after several more times with the check eng light on for a couple of days and then off for a couple of days, the dealer sent it to a specialist who replaced the O2 sensor! I am not anticipating anymore "check engine light' issues.
  3. Update: Light went off last night. Did not come on into work this am. Maybe/hopefully the mechanic was correct.
  4. My check engine has come back on. I had it at the dealer last week and the error message was P0420 Catalyst System Inefficiency. They claimed this was caused by misfiring from last time when fuel got into converter not completely burned. I bought the car (used - 87K miles) at the beginning of the month and two days later the check engine light and the trac control light were on and it ran rough. The diagnosis at that time was that a spark plug was fouled due to the steam cleaning of the engine. After replacing the plug, everything ran fine. Now if I am to believe them, this problem should go away. However, how can I reset the check engine light myself, without taking it into the shop? Thanks. 97 LS400 (want to be) Happy Owner
