Engine Performance problem
2001 Honda Civic 4 cyl Front Wheel Drive 124000 miles

This problem just started on Sunday, while I'm driving sometimes if I attempt to push the gas to go faster it will not let me the car won't accelerate but, it still sounds like it is but the speed starts to drop. And my engine sound bad almost like there is a tick or something now it's very loud and as I said this all started on Sunday late afternoon as I was traveling on the interstate about an hour to two hour drive.

Please help!
