Hey guys New to this site. Just traded my 2002 Trans Am Collectors Edition #504 for a 2010 Camaro 1SS Black L99 A6. I have always wanted a Camaro and finally broke down and got one since my T/A almost got me killed.

I have noticed an irregular idle with the Camaro. It will jump between 500 rpm and 800rpm and give a little shake. It does not happen all the time but it is getting more frequent. I am a little worried about it so any feedback would be great.

Hmm, mine has been rock solid smooth from day one. I think the idle is set too low personally. A little ways down the road I used a Predator to turn off the AFM and bumped the idle speed up 100rpm and it was perfect.

I carried that over when I had the SC installed.

+1 for having it checked out after you put about 1000 miles on it.

The dealer might have put something less than 92 octane gas in the car. Even when you fill with super the engine does automatically reset (or takes very many miles), you need to pull two fuses and leave it overnight. Not sure as I am writing this which fuses they are, do a forum search. Mine still had a bit of a shake "sometimes". When I purchased and installed the Diablo tune I up'd the rpm 150. Now it's very smooth.

yea it is possibly a low quality fuel issue. try and do the "fuse pull" trick to reset the computer.

run your tank as low as you feel comfortable
fill it up with premium (91 or higher octane)
go home
open the hood and fuse box
pull the #5 and #20 fuses (labelled ECM)
and keep them out overnight
put the fuses back in in the morning
turn the car on and let it warm up
then go drive around and see if it isn't as smooth as a baby's bottom!

be sure to ONLY run premium fuel... the car will run like crap with regular, leave that stuff for people with Mustangs ;)

Yep. We have a little cam lope on the SS, but this sounds like bad gas. Run the tank down, Fill up with GOOD premium fuel, pull fuses 5 and 20 for an hour or so. Drive it like you stole it for a bit. All will be well.

That sounds about right. The guy who sold it to me said "You know you can run 87 in this thing." :confused: I looked at him and said thats Stupid! I traded an 02 WS6 Collectors for the Camaro so I am familiar with how the L series motors run. Only 93 for me!!!! :thumbsup:

I am going to do the fuse pull while I am stuck at work for 9 Hrs. Thanks for all the help guys.

I pulled the #5 and #20 and let it sit for a few hours. It is still going on :angry:

I am taking it to the delarship to see if they know whats going on. The car is also ticking on start up. Not the usual piston slap or valve tick the L series has. There is also a vibration at a low throttle position when crusing. It might be a bad motor mount or faulty motor. Thank God for my GM factory Warranty. :thumbsup:

How many miles on this car?

Ticking at start up: reduces as engine breaks in, although it still happens sometimes at random. It all depends where in the cycle your AFM pistons stop at shut-down.

Vibration: definitely goes down after 2000 miles or so.

Vibration at low throttle: that's just what 4 cylinders at 1000 rpm sound like. Switch to manual mode, and you won't drop into 4 cylinder mode at low rpms.
