Hi guys....

I've noticed excess vibration while I'm idling in traffic.. being that I'm almost ALWAYS driving city (and thus, my best gas mileage has been 17mpg), it's really irritating.

Anybody else have this problem? Should I take it in?

the car i test drove shook a bit at idle too... especially the shifter

yeah, my shifter has the shakse at idle also

My shifter shakes a little but not enough for me to worry about. What is your definition of "rough idle" and how bad does your shifter shake?

Ahhh, the dreaded rough rotary idle. By lightening up the rotors in the Renesis, I am suprised this hasn't been more of a problem. Considering how important the balance of the rotors are, and the Renesis using light rotors, would even the slightest carbon buildup cause a vibration at idle? I keep hearing about the rich a/f setting at high rpm, which will leave alot more unburnt fuel in the engine, especially with exhuast side porting instead of periphial porting. Wasn't that the point of the side exhaust port- to aloow the unburtn fuel to stay in the engine? This could also lead to fouled plugs-- either way, maybe it is time to start mixing some MMO in the fuel for your Renesis?:p

So what should I do? Should I take it in, or is it something thats normal?

my car only has 130 miles but i have noticed something odd,the car i test drove first before mine arrived had the shifter shake at idle but did not idle rough.my car i bought yesterday does not idle rough either and still has the shifter shake but is only half of what the first car i drove was(if that makes any sense)by the way,i love this car.
