Bad Gas?

Sorry, but no joke. We had a run of bad gas in my area last summer. Water got into an underground tank at a gas station and messed up quite a few cars. Just a guess.

Eh that would cause a little more than a slight knock in the engine.

I would say the sputtering is not normal. I would have it checked out.

i'd also get it looked at. could be your fuel injectors as people have mentioned. i'm just guessing here, but it could have something to do with your MAF sensor. do you have anything aftermarket on your intake? have you changed your air filter recently?

I have the same problem with my 04.5 6MT. I think the knocking sound is from the shake of the clutch due to random jumps in idle vibrations (engine sputter maybe?). Also, my check engine like went on yesterday too...which i think usually means a problem with the emissions. I have a K&N filter installed that i'm going to swap out for OEM this weekend. Hopefully this will help.

I am having the same problems with my 04 6mt as well. I have put fuel injector cleaner yesterday. The problem got alittle worst when I went from the stock intake and swapped for the z-tube. Any Info on this is appreciated.
