Rough idle Help
My Auto 2SS seems to have a very rough idle. This happens in park and in drive at a stop. Has anyone else had this issue? Any suggestions?

My new SS auto also seems to do this. Quite often during start up and sometimes later when it should have already been warmed up.

Any ideas? My '66 Chevelle Conv with the big block and a simple HEI ignition doesn't idle this rough, feels like a miss... I don't have a CEL but can't believe this is "normal"...

To follow up, we took the wife's '12 SS auto vert on a road trip (1200) miles this last week and hers does not idle rough nor does it surge and lunge under normal highway driving, as mine does... Any suggestions?

LOL...I wish it was a cam... If this were my 66 Chevelle, I would say it's a miss but with all the electronics and computers on the new cars, i am reluctant to muck around with anything...
While I didn't buy the car for fuel efficiency, hers also gets 3-5 mpg more than mine... |

I have the same rough idle issue. I have the L99 and assumed this was just the AFM?

Hello bombgolf,
I would suggest getting your vehicle in to see a dealer for an official diagnosis of this situation. We will then have a better idea if there is a actual issue and also have it documented for future references. If you decided to take it in, I can help set that visit up for you. Let us know, here to help. Reggie B. Chevrolet Customer Care

Is the rough idle new or has it always been this way?
How many miles? If you put it in park does the rough idle diminish? Does it go away?

I took it to the dealer today, great service from my dealer by the way... I had a bad O2 sensor (but no CEL) and they think a bad torque converter... Have to take it back next week... |
