Hey guys, I am noticing that my 6MT will sometimes drop down to 500 RPMs when I take it out of gear. It especially happens when I am in 1st going like 7-10 mph and let the engine brake the car and then throw it in to neutral. When it gets to 500 RPMs it will vibrate a little bit and then go back up. Also, I just installed a new battery and my idle RPMs hover right at about 600 RPMs.
Could this be a dirty throttle body? Or should I reset the Idle Air Volume and ECU? Thanks!
