My 02 ss runs a lil bit rough on start up. After a few secs it runs fine. What should I do before it gets worse?

 

How long has it been since it had a tune up? may need a new set of plugs and wires

I would also run the tank low and when you fill it up put a can of seafoam in the tank and run it through, it could be a carbon build up, or bad gas. This is a cheap fix that may work and the one I would try first, as plugs and wires cost money lol,

 

I agree with Ken. A good tune up. Sea foam in a Fresh tank of gas. Check all your wires for cracks and dry rot. Also have your PCM scanned for stored codes.

 

Thanks for the advice I appreciate it. Just bought the car so not exactly sure when the last tune up was. The seafoam works good? I never used it before. I'll try that and check my plugs and wires just to be sure.
