check to see if you are throwing a code. I don't think the rev limiter should be at 6200 on a H22... I have a 99 and the redline is 7400 and rev limit is at something like 8200. I don't know if 4G ludes are different, but it's the same engine so I don't think so. Also, make sure you are at normal operating temperature. I got rev limited early because the engine was still cold.
