The other day I started up my Camaro and the RPMs kind of jumped from 1000 to 1100 periodically at idle. At idle, the car also vibrates, a little more than it should. Any ideas? Anyone else in the same boat?

Idle Air Control?

what do you mean? what is that?

get some seafoam and follow directions, has the fuel filter been changed? How about tune up?

You guys have winter too, correct? Everything vibrates more in the cold. Could be one explanation.

blue89vert

i guess

paarman97maro

I wasnt referring to the idle, although you Idle higher in the winter at startup obviously since its colder... But as far as vibrations go, winter has a lot to do with it.

Cold weather makes everything shrink so the pistons are really tight in the winter. but after it warms up it should be ok

paarman97maro

contract, I think, is a better word for it haha.

Yeah winter makes a few extra noises and whines.. I know starting it in the mornings when its been 5'f outside makes the alternator whine a bit.

If its really idling rough id try some new plugs and wires if it has been awhile..

mxracerbrian

yeah that should help. how long has it been?

my car always rattles a little when i start and its cold out side cold just makes metal contract so some stuff rattles and stops when it warms up

blue89vert

whatever floats your boat

Im just saying.. when I think of the word shrink, I think of getting smaller (ex. t-shirt in dryer), which is not the case here.
