Actually dont rule out the fuel pump mine did the same thing due to a bad conection to the fuel pump and with a 5 sp trans you tend to jerk when driving alot more = fuel hitting the pump and conections more violetly. its pretty easy to check there is a fuel pump access panel under the carpet in the trunk its the circle with all the hex bolt around it. so if those other suggestions dont work take a look at it.

Btw no new pump was needed just some new connectors and i was off.
