Well, when driving it has bad vibration and during small hills 4th and 5th gear won't quite make it. and even 3rd has a hard time doing so. so i'ts basically losing alot of power. and need to know what u guys think. not a very long post but wanted to get to the point. thanks

 

depends on your definition of a hill. It may be a mountain to me if you live in Colorado and I live in Nevada.

But it does sound like you are losing power. When it vibrates what RPM are you at in 5th gear, and in 4th gear, and then in 3rd. Need to know to help out.

what speed are you approaching the hill? Where does it sound like its coming from - or only vibration. If so, how bad?

 

dunno what type of vibe your feeling but try this

hold your brake with nuthing around you put your car in gear and give it some gas not too much it ez with an auto see if you feel it there and see if it feels like a miss could be a bad plug/wire/coil
