Today i had to get out the driveway really fast. I normaly let the car warm up for at least 30 sec's or so but not today. It was a crisp 20 degree's outside so i was driving around in first at around 2,500 RPM's just to give it a sec to warm up. but the car was bucking like crazy! It wasn't like i was pulling off the gas and it caused the bucking, it was just straight throttle, holding it on the same position.

I'm getting close to my next oil change, and was concerned about the "white sludge" that had appeared in my oil (although common in cold weather from what i've heard) I thought maybe this contributed to it, any ideas?

the white sludge is nothing to worry about, it is created outside of the crankcase (sump pan, what the heck is it called on a rotary, oil pan i dunno) and the bucking probably is from the ECU trying to control the mixture and the engine timing, a cold engine thing...preferable that you warm it up, but prolly not serious if you dont.

 

Yes, sounds like you are over choking youe engine.

The choke is still on. The you add gas while at the same time your putting a load on the engine by driving it. It's starving for air.

The car is gulping for it's life.

2) You are causing condenstion and water build up in your car by not warming it up. Very bad for wear and tear. That's why the white foam appears.

Good luck planning a couple more minutes in your schedule to warm up the car.

 

Gotta have those 20-30 seconds. It's very little time up front that will save you in the long run... who ever said rotaries didn't need a little special attention?!

 

read the the sticky in the known issues section about the foam. then read the tsb about it also. your car wasnt warmed up thats what was causing the bucking at 2ish k rpm
