Hey guys, I have an issue with my N15 sedan and am unsure where to begin. When coasting along in first, second or third at around 2000rpm, the car bunny hops rather violently. It only seems to do it when it's warm. I vaguely remember reading something on the old site about the throttle position sensor being a possible culprit? If someone could shed some light on this that would be fantastic.

Thanks in advance!
