rough idle

I have an 03 3.4 with a very low rough idle.Hopefully this seafoam will work.I have already changed the pcv and no luck with the idle...

 

Ok, so for those interested a bit of an update. I installed the oil catch can, and its working fine. Ive put about 50 miles on it and this is what was in the can..
Still have a rough idle in drive though. really racking my brain on this. Im gonna pull my new plugs tomorrow and see what they look like. They've got about 1500 miles on them. Could the rough idle be attributed to any tranny problem? which btw mine is fine. No slipping or anything..

 

oops, double post

 

Has your idle problem been taken care of?My 03 still has an occasional low idle..

 

To give you the best answer, not really. Its better than what it was. Read this thread i started.
