September 17, 20169 yr I am working on a 2007 Outback, 2.5 Auto, 213K. It belongs to my niece (owned since new). She took it in for routine timing belt replacement at the local Subaru dealer. Drove it home and it had no power. Only ran "good" at part throttle. Took it back and Dealer says the CAT is plugged up. (All the sudden?) Now her cheap husband refused to replace the O2 sensors (which had been throwing codes for the last 70K). Now she asks for my help. I replaced the cat with a Walker replacement. Same issue. Step on the thottle, falls on its face. Only codes are for O2 sensors... but the cruise light is blinking. I'm thinking the dealer put the belt on one tooth off. Your thoughts?
September 17, 20169 yr Timing sounds off Imo. A cat wouldn't suddenly get clogged after doing a timing belt job.
September 18, 20169 yr Check the timing marks and see if they line up. If it's not the timing the o2 sensors can make them gutless and buggy sometimes. This would be the next logical step to fix the problem. How recent are plugs and wires?
