Idling rough and spits and spudders

Question:

I have a 2001 Oldsmoblie Alero GX and it is idling rough and spits and sputters going down the road ,but not all the time. Got any answer of what it might be? I put it on scanner and it was saying something of a low spark issue and there isn't any check engine lights or anything lit up on dash.

Answer:

Sounds to me like it needs a good tune up. A new set of plugs should help it out quite a bit. If the check engine light is on there may be a different issue that will require the use of a scan tool to get the codes. http://www.freeautomechanic.com/scantools.html
