I believe this problem is destroying my engine. I have no other means of transportation so I have to drive it. My engine was idling super high and I was told to replace my fuel pump. I did that and 2 days later it is doing the same thing maybe even worse! (The pump alone was 230 dollars!) I have also replaced the O2 sensor. I am still paying on this car with no warranty (WHY!!!) I have gotten over my head with this car...they are high maintenance!!!!
