Hey everyone, I'm totally new to these forums, and pretty new to WRX ownership, so bear with me.
While accelerating in my 2008 WRX sedan, i've noticed a very slight lag in acceleration around 2000-4000 RPMs. It almost feels like something in the car is slipping for a second, before picking right back up again. I haven't installed any performance parts, the car is completely stock.
Any idea what this might be? The only thing I could think of is it might be a transmission problem, but I find that unlikely, considering the car only has 15,000 miles on it.
