My civic has been treating me great until about six months ago. About that time it started with this strange grumbly whining sound whenever it was in gear and driving, mostly when accelerating. About a month ago, I noticed that I had a very small range of accelerator-pedal motion in which I could accelerate. If I pushed the pedal past that, the engine just revved like it would if the clutch pedal were depressed. About that time I noticed that the grumbly whining sound went away. Since then, on only one occasion, the grumbly sound returned and my acceleration returned to normal.
So, basically, it takes me about 20 seconds to get to 60mph from zero, and I have a hard time getting much past 70mph on the highway. The engine is running fine, the issue is that it seems that not much power is getting to the wheels. Can anybody help me?
Thanks,
Nate
