Lately my 04 srt4 sputters during acceleration. For example, when I'm driving at 70 or 80 mph and going to pass another vehicle it will make a sputtering noise. It only happens once in awhile, not all the time. My boost gauge doesn't fluctuate all over the place, it stays steady around 12 lbs. I've checked all vacuum lines and no loose wires. Could it be a boost leak? Any suggestions will be appreciated.

 

Check your spark plugs? Fuel pressure should be checked as well.

 

ok, I ordered new iridium NGK through ebay and I will change them out and see what happens. thanks for the feedback!
