First time to get my fingernails really dirty! Changed the oil, FD fluid, transmission fluid & radiator fluid. Put in a HID low beam and added PIAA 1100x. Put some Hyper lites on the back! Here is the problem, when I start the engine it revs up around 4000 rpms. I can get it to go to 3000 but have to work hard on the throttle. Any thoughts of what I did wrong?
