Last week marked two years since I bought my car at a local dealership and lately I've been getting use to the fact I've put already 25k miles on it (which is a little over the normal 12k/year) and it's starting to show some age compared to when I bought it. I mean i'm not bitching about the car saying it's doomed or I didn't see this coming, it's just small are starting to show themselves. One major thing is the throttle. I can remember when I bought it, I would just tap the throttle ever so lightly and the car would smoothly accelerate without a hitch. Now when I tap the throttle ever so lightly, it's jumpy and there is no smooth transaction of acceleration. What's up? Is this a sign of my clutch going bad (5spd by the way)? My cheap airfilter finally showing it's cheapness (I'm poor and it's all i got right now, lol)? TPS need adjusting?
