hi brought the car to lexus dealer they cleared all the old codes that got rid of the engine management light

hello and welcome to you too - I must have missed your "hello" post somewhere...... get the fault code read then go from there otherwise you are just guessing, and if you reset the ECU to turn the lights off you are also wiping the fault code
