My car is a 1999 Lexus IS200. The car drives beautifully, no rough idle. However ocassionally the car just misfired, engine check light came up. If i was driving at speed of 40km/h or more, the light will be there for few seconds and the car came back to normal. If i was driving less than 40km/h. The car will go to a complete stop within seconds ( power steering cut off and everything). I put on scanner three times. 1st time it came out as short curcuit on oxygnene sensor, 2nd and 3rd time it came out as igniter malfunction Most of the car service has been done by Chatswood Lexus. Spark plugs and coil packs have been recently changed. It will be a great help if anyone might know what the problem is
