hMMM i dont have an up or down rpm when idle.... well sometimes i do, but it is like 1 time when it gets cold outside a year... but that i think might be norm. I do notice though when im "punching it" or racing someone that second gear is all sorts os shitty at 4000+ rpm. That use to be my best gear but now third gear is and even that gets shitty after about 5000. By shitty I mean it feels like rocks are going through my engine. I can feel it in the gas pedal, and I notice it in the acceleration of the car... just has that feeling of slowing down i guess i dont know how to explain it.... if that makes sence?¿ I dont know.... im just affraid to take it to the dealer and have them tell me what the problem is and then "fix it" and have it feel the same way! I am just going to pin point the HP issue somehow
Im still going to check them sparky plugs and probably just change them out anyways... 120,000 miles seems to be a good time to do it at
