Tonight (for some reason), I speant some time listening to my idle. I noticed I have particular off noise coming from the normal idle sound. It kinda goes brrrrrrrrrrr....bump..bump.bump..brrrrrr...bump... . Not in any interval..not very loud...just a brake in a smooth idle....is this normal or do I have a spark plug misfiring (or something else)?

Normal to spudder a bit. Mine always has.. So has everyone elses I know.

Thats what I thought....I was just surrounded by V8 guys who were saying...thats not normal!!

Well there's your problem, your listen to guys who have CAMS...

LOL. Yeah. Your car should be fine. If it's REALLY drastic... Like the RMP needle jumping bad... then you should look into it. But if it's just light popping and sputtering... that's just the beautiful sound of the Rotary!

When I was driving mine around town yesterday I stopped at a red light and mine started idling bad and died. It started back just fine but I had to keep on the throttle at rest for the next two lights. After that it was fine. What's up with that?

check your map sensor.

Or your clutch switch. Power FC seems to be very sensitive to that for some reason...

map sensor? Explain please https://www.nopistons.com/forums/pub..._DIR#>/sad.png

its normal for a rotary to idle like that, they seem to run badly under no load?
