My car for some reason seems to have very little or no power at all when the rpm's get above 3,500. It screams all the way to 6,000 rpm's but the entire time it goes through that range the car doesn't seem to go faster at all. When you get on it from a complete stop it will put your head back and you can feel its power but if you are just cruising and then floor it, it will drop down a gear but does not seem to go any faster. Sometimes it also shifts gears extremely hard. Also the service engine soon light stays on and I have plugged a code reader into it that says P0138- o2 sensor ckt slow response (bank 1, sensor 2) and P0138- o2 sensor circuit high volts (bank 1, sensor 2) From my own research people with similar issues with this car have suggesting cleaning and/or replacing the mass air flow sensor and that replacing the o2 sensors did not solve the problem.
