As posted in discusion forum took a trip to Tn. and back 350 miles over the week end and while up there the car ran as usual.Car ran fine both direction and was normal power wise while there but after getting home it runs and drives like normal but has no power very sluggish but no codes or lights and all guages normal any thoughts would be appreciated.08,a6,A&A kit, long tubes cat bacs.Could it be possable that the cats could be stopped up?

 

Tis possible

Need someone to log it, or at least get some wideband and boost readings to see what is going on.

 

Check all of the connections on the blower piping. If a coupler came off it will drive fine with no codes but will be down on power. Cats clogged is another possibility. Collapsed air filter is another. If all of that checks out time to run some logs.

 

After thinking about the air filter and the rain storm i drove through on the way home and the next day i ran it through the drive through car wash i think the K&N was water logged.I have now cleaned and reoiled the air cleaner and am back to normal.Thanks all for the thoughts.
