Default Rough Idle

Just changed the oil, ran the car around the block and check engine light is on. Rough Idle at 500rpm. Anyone has any idea what it can be?? I don't have a code scanner to investigate the problem. Just got the car out of the shop a few weeks 1.5 weeks ago !! It just turn 50k too !! Any thoughts are much appreciated. I would like to know what the problem can be before i take it to the dealer.

Need more details. The idle is controlled by a lot of things. What was it in the shop for? Any other recent problems?

It was in the shop for a rear leaf spring that busted. Where can i get one of those code scanners that everyone seems to use? How much should i pay for one of those things. I can't really give more details. It only idles rough and there doesn't seem to be any other problems besides that. I was wondering whats the most common failure for a problem like this? It almost doesn't matter.....i'm just going to bring it to the dealer tomorrow morning.
I need to buy a beater and some tools. The money i spend at the dealer cost just as much!! :mad :mad :mad

Do the easy stuff like check for a plug wire burnt or fouled plug. Also look for a vacuum leak which all of whitch will cause rough a idle. I bought a Auto xry from Kragen for about $150 which makes life easier as it gives you real time data along with trouble codes.

a Snap-On scanner will run you about $2500.... It could be a number of thints and you need to get the code out and see what it is and go from there
