My check engine came on and I had it diagnosed. I had the O2 sensor (Bank 1 Sensor 2) replaced in my 98 Lex GS300. The car ran fine for about 20 miles then the check engine light came on again. I had the check engine light reset and again within 20 miles the check engine light came on again. What could be my problem?
