What do you think I should try next? Thank you
Engine light has been on for almost three months. Mechanic first put in an after market throttle sensor then replaced it with Hyundai part. Still on. Replaced the Mass flow sensor with an after market then replaced it with Hyundai part. Light is still on. they have hooked up three computers and a tablet to this car and nothing. The guy dong this is supposed to be a top gun in his field and he is stumped. Next wee he is going to clear out the mother board and reprogram it.
