Slight idle shake - Normal?
I have a 2001 Mag Red A4 Coupe with 2000 miles, no mods, yet. It is a great car. After the car is warm, sitting at a light I feel an intermitent shake in the engine idle that moves the whole car very slightly. Like a slight miss. Is this normal? The car hasn't been back to the dealer yet and I'm wondering should I take it early to fix this?
Thanks,
Carmen

Re: Slight idle shake - Normal? (CSDMagRed01)
I have a 99 with auto trannie and my car really doesn't idle very smooth also.perhaps its the cam or its just the nature of the beast.when I take on the freeway and drive it rather hard (high speed only) the engine smoothens out some what. your car may need to be blown out--- get the carbon and gunk out of the engine . do you drive rather agressive or are you babying the car? :chevy :flag :flag (stars and stripes forever) :flag :flag :chevy

You may check to see that your plug wires are attached firmly. I had the same problem on my 2001 and Cyl. #8 wire was loose causing a slight stumble at idle.

Mine does the same. I figure since it idles at 500rpm in gear, it's gonna shake from time to time. That's a pretty darn low idle.
Sounds like a normal condition. :)

Re: Slight idle shake - Normal? (CSDMagRed01)
I have an '01 coupe with about 2K miles also, and it too has a little roughness at idle. Twice it has had what I would call a dead miss sitting at a light (the non-firing on one cylinder), but I have no intentions of taking it in to be looked at and I'm not going to worry about it. It runs fine otherwise. I also get a gurgling noise when starting the engine while cold which sounds like it is exhaust related. For the most part, it goes away after warm up. Do you experience this noise? :seeya

No gurgle here but I do have the "shaking of the beast" at rest that others are talking about. As my 15 year old daughter says, "I love that sound". Dragon purr... :lol: :lol: :cool:

Re: Slight idle shake - Normal? (Austrian Vette)
Normal.
My 99 camaro SS w/ls1 was a bit rougher then my 99 Vette w/ls1. I think it has to do with the camshaft profile. More spacifically, the lobe seperation angle.

Re: Slight idle shake - Normal? (CSDMagRed01)
I wouldn't lose any sleep over it...my '01 has had that shake since new, and it can't be running that bad since I cut a 13.06@106MPH tonight at E-Town with stock exhaust, stock intake and 2.73 rear gears..... :D :D :D

Re: Slight idle shake - Normal? (NJVetteGuy)
Thanks for all the feedback. I've owned the car 4 weeks, and probably am babying it alittle. It runs great though. My first Vette in 30+ years; don't know why I waited so long.
