Lost Power in 2011 V6 - Help
I have a 2011 2LT RS Camaro, stick shift, that I bought new in May of last year. I have 22,000 miles on it.
When I first got the car I would ride it hard all the time. At one point after about 5,000 miles I checked the 0-60 time with an accelerometer. I was consistently running between 5.8 and 6.0 sec. I didnt check the 0-60 time again after the first 10,000 miles. I was consistently getting 21 mpg during that time. I was always using 89 octane gas.
After about 15,000 miles I got over the need to constantly race and began driving conservatively to improve gas mileage. I started using 87 octane and began getting 24-26 mpg for a tank driving mostly highway miles.
I can't say exactly when but it seems over the past 3 months?? I noticed a drop in power when I went full throttle. I particularly notice it at high rpm. I decided to use the same accelerometer that I used the first time to recheck my 0-60 times and to my horror I was now running between 7.5 and 7.9 seconds.
I looked back at my maintenance records and have changed the oil every 5,000 to 6,000 miles. I did notice that I never changed the air filter. I changed it today thinking that was probably what was wrong but noticed no difference at all.
The only other factor I can add is that do to so many drag runs early in the cars life I did burn the clutch a little. It will slip if I try to power shift. That still doesnt explain the drop in performance because I can still quick shift and feel the pull after the shift. I may have lost 0.5 sec max from that. Other than 0-60 times the car just doesnt seem to pull like it did between 4,000 and 6,500 rpm.
I would appreciate any suggestions.
