I have an issue with my rsx-s where in low gears (1-4) the rpm's will jump from 3500 to about 4000 when I accelerate without putting any power to the wheels. The horsepower kicks back in as soon as it hits 4k rpm, so it isn't wheel slip. Another problem I've been having in is 5th and 6th gear on the interstate. When you accelerate and hit just below 4000 rpm, the revs hold steady and no matter how much gas I give the engine, they won't climb any higher. It can't be the rpm gauge because it goes well above 4000 in every other gear, but won't in the higher ones. Please keep in mind this is a 6-speed manual, not an automatic. Thanks!
