A couple weeks ago, I came to a stop at a light and noticed my idle was fluctuating from ~1000 to ~1600 back and forth. I could get it to stop (sometimes) by giving it a few good revs.

This only seems to happen every so often; definitely not every time I drive my car.

The higher revs i'm doing in attempts to get it to go back to normal. ;) Any idea's? It doesn't seem to be negatively affecting anything that I can tell.

are all of your plugs firing? the way its revving makes it sound like the engine internals are okay...

there are a couple things that the first few years of the rx8 had that were weird maintenance items. coil packs were one of them.

it could be a vacuum leak, though doubtful.

oil pressure good? air filter good? does the power delivery feel any different? no CEL?

Turns out its just the neutral switch going... Thanks though!
