Hey Guys...The trac has been running rough lately. Started out as an occasional bump, kind of like someone hopping around in the engine bay. Tried to retrieve some DTC codes and nothing comes up. Cleaned the TB, IAC, and did the seafoam in the brake booster line and gas tank. Didn't fix the problem. Today while driving home, seems like the bump occurs more rapidly as opposed to occasionally. Engine sputters slightly upon acceleration as well, and there's a different tone to the exhaust, more throaty/raspy/sputtery instead of the normal smooth tone. Tried to retrieve DTC codes again today and still nothing comes up. Engine idles fine with no fluctuations in RPMs, just can figure out what the bumping and exhaust tone is all about. Also tried changing up the xcal tunes, and it does the same on all of them. Any ideas?
