Hey guys I recently have had a random loss of power. Driving home from a friends on the highway I decided to floor it and my exhuast sounded deeper and my car was just going a lot slower. RPM's were rising as usual but it was just going extremely slow. So I put it on a reader and the only thing that came up was oxygen sensors. So I replaced all 4 and it got a little faster but still really slow. Check engine light is still on after clearing the code but it is not reading anything else. My car is an 04 5AT and I have no clue what it possibly could be. I'm currently at 120k miles and I have a buddy who has the same year and 5AT at 100k with the same problem. Any ideas? Is this a common problem? Anything will help. Thank you.

 

Could be a bad camshaft position sensor or crankshaft sensor. Those are known to start to go bad and not throw a code. Are either of you suffering from hard starts or rough running engines? These are warning signs that one or more of the sensors are starting to go out.
