Hi, this morning on the way to work I was driving along and got stuck behind some idiot driving far to slow, i over took them in 3rd and I think I hit the limiter although I didn't see the rev counter at the time..

Anyway as soon as I thought I hit the limiter, the car just died so I bump started it in gear and it went again but there was a very loud knocking/tapping sound coming from the engine, I couldnt go over 30mph and didn't know what I had done wrong, I was told rst's don't like the limiter and I did do it by accident..I'm worrying that I'm going to have a big problem, would
Anyone know what I'm talking about sort of or have any idea what it could be?

The car starts and runs but sometimes it will cut out, I did drive it a mike or so to get to work so it's drivable..thanks
