My car has a check engine light on with code indicating that My EGR valve need to be replace. The Auto zone associate diagnos the car and that's what he concluded. I replace the EGR valve and reset the computer in the car by unpluging the baterry whlile the engine is off 8 times. I did the hundred mile drive it still come up. The vehicle still shake or chokes on Idle position and it consume a lot of gas too. And another thing the car does is when I am doing 70 mph on the High I feel a drag or resistance as if its pulling or towing something. When I remove my feet off the gas peddale the vehicle looses speed momentum very fast as if I was down shifting on an mannual transmission you can hear the engine humming too. I was told it may be a bad oxygen sensor or an Engine control valve. Can some tell me how many Oxygen sensor does a toyota corolla 97 have? What is really wrong with the car? Thanks!
Feel free to E-mail me too about it.
