when i got my TRD muffler installed it started doing that. i think it's just normal. same thing when i had my civic and the apex'i N1 exhaust.

yup usually happens to me when i let off the gas and am in neutral coasting. rpms drop to ~700 then up again, down, up whatever.

it's probably just the idle air control valve kicking in after the rpms drop. Almost all manual transmission cars do this. It's not a problem unless it bounces like that at idle.

I believe it's the computer learning the air/fuel ratios.. my car does it alot more after I reset the ECU.
