The 2010 Camaro LS3s have the random mild miss at idle
just like EVERY 2003/2004 Cobra I have ever owned or seen..
No big deal..
I started to ask if anyone had tried running NGK iridiums and if it smoothed out the idle any....they helped the idle on the Cobras I've owned.
Nothing I can't live with,not bad at all,but if it can be a little smoother with a plug change that would be great...
I've had big cammed cars....if I am going to have a rough idle I'd like the lope to go with it.
I don't think it is the cam itself...but more a combo of factors including the closed loop fueling cycle...during closed loop the ECM,using the O2's, is constantly adjusting to maintin stoich...this causes the fueling to cycle lean-rich-lean-rich..the partial miss you feel every few seconds is the lean swing in that cycle..
Cam might be part of it...but the cam isn't radical enough to account for the miss by itself jmo..
Again,it is very mild IMO..
