2001 Hyundai Santa Fe Won't Accelerate Properly

I have a 2001 Hyundai Accent in my fleet of junkmobiles. I had that same problem and replaced the O2 sensors on the exhaust system. I did not have a hole in the exhaust but you might be able to get some muffler tape that will keep it going for a while. To be honest, it sounds like you need new exhaust. All of these current engines, regardless of nation of origin, are controlled by a computer which tells the injection system how much fuel and air must go through the system. They need input and they get that from the sensors. If you are a graduate student then you are quite capable of figuring out what is wrong. All newer engines are controlled by a computer and sensors as far as intake/exhaust and if you know that you will figure out a fix.

Unfortunately, my particular graduate program in Counseling Psychology and Psychiatric Institution Reform doesn't go over car mechanics. Rats! ;)
