Every once in a while when I'm accelerating through first gear after a normal start and normal acceleration the RPMs will jump in 200 - 400 increments instead of a steady increase through the RPMs. It doesn't happen all the time but every once and a while and only in first gear. Is anyone else experiencing this? I have an '06 SS/SC G85 with 2000 miles on it.

 

drive by wire does that from time to time

 

I didn't even know that the car was drive by wire, do you think it might be a sensor problem?

 

no its just really touchy from my experience

 

Yeah, every once in a while mine get jumpy too... you just get used to it.

 

Mine has not done that since I go stage 4+ tuned right. I think here is a problem with the GM tunes under idle, and light duty.

 

mine does that every once in a while, my girlfriend freaked out when it did it while she was driving because she thought she messed something up haha

 

say bye bye to your clutch sir!!! lol i had the same problem and i would say you got about 500 miles till it gets really bad and then you will need a new one asap!!!

 

Nonono mine did it when i first got it and have put 23k on it. he is not describing clutch slippage from what I understand he is describing power surging.

 

yes just the car being junpy in first gear

 

Yeah, its not slipping I don't think, its just a jump in rpms after the clutch is already engaged.

 

I have the same problem on very humid and rainy days. GM tech tell me it does that when rain comes in Supercharger, it skips detonation in cylinders.

 

Um... what?
