fortariq Posted November 13, 2008 Share Posted November 13, 2008 I have had the check engine light due to the O2 sensor for about a year. The car has been running fine till this morning. The check engine started blinking in the drive(steady in the park) and drive became rough. It felt like the engine was vibrating. I was able to drive the car but it drives heavy. It's '99 RX300 with 100K miles. Before I take it to the Totota dealership, I could use your help. Please help. Thanks. Quote Link to comment Share on other sites More sharing options...

Have you taken it to have the codes read (or done it yourself) . I'm sure by now you've figured it out but it'd be interesting hear what it was.
