Hey guys, I'm having a slight problem with my 5 speed 05 GT. My engine speed will often dip up and down from 350 - 1100 rpms when I'm sitting at a stop light or while I am braking while I am approaching an intersection. It hasn't entirely cut off the engine yet, but I'm concerned that it is a problem that will only get worse. Any suggestions, stories, similar problems, or even better.... solutions? Thanks

It is happening to me quite often... I did forget to mention one thing, in my original thread... My car has roughly 14,000 miles on it... I was using 93 octance gas until I read in the manual (12,000 miles) that it was not engineered to run 93, but was engineered to run 87 octane, does anyone think this might have anything to do with my problem?

Thanks for the tip JetBlack, I'll have the dealer check it out... really appreciate it, it does especially happen when I apply the brake, I have noticed it more in since it has gotten cold up here. sorry twoScoop... Manual

So listen to this, i brought the car in to the dealer yesterday regarding this problem... the dealer told me that he retrieved a memory code for frost in the throttle body or something along those lines.... I asked him how this could have happened, he said well you have a KN air filter and it may allow moisture into the intake and when the weather gets chilly, this is the problem is the result.... AHHH!! Then one of the techs badgered me a bit and asked, "So why K&N?". I could only answer him with their for promise less restrictive air intake, he said i shouldn't believe everything i hear. He's the expert I'm not, I'm putting my stock air filter in, this sucks!

I really don't know what to do, it is put away for the winter so I'm just gonna see how she runs this spring... if the problem persists, i'm gonna keep bugging the dealership til they do something about it.
