So ya....im driving along like any other day, well excpet its like 97 degrees out...but other than that its any normal day. I come to a stop, light turns green, i start accelerating in first gear, as soon as it gets around 4500 rpms the engine just like holds itself back, it wouldnt let me go any higher. It was like it was being restricted or something. Really weird. So i shift into second, get around 4500 rpms, it does it again. I was like wtf. So i get to the next stop light...turned off the car, then turned it back on again. Everything was back to normal, i reved it all the way up to 6500 without a prob. Anyone know what might have caused it or what it may even be? Its not like my car was hot or anything...i just pulled it out of the driveway. But i havent had the problem since...weird stuff! haha. Thanks!
