On 99 ES300 I recently acquired, CEL showed misfire on 1 and 5, I have 77,000K and possibly never had a tune up. Could it be just Spark Plugs and wires or something more serious. If that's all that came up on the reader and not a Sensor than that should fix it right? CEL would still have to be reset though? Also Trac Off Light came on, I disconnected the battery and light has not came back on. Did that reset Trac or I still have no TRAC and the light is off. I don't know, please help . i just hope a tune up and a reset will solve my problems. I just got the car a week ago. It was a hot deal though.
