Hey guys I have a 2001 Subaru Outback 2.5 automatic, it's been great all up until three days ago,the car had a hard start and the idle is a little tougher, when put in drive it will coast forward but as soon as I put pressure one the gas pedal it seems to chug and bog down, sometimes even shut down. It's not throwing a cel. I still plugged in the coder and it's showing problems with o2 sensors, cat, hrt and evap. Any suggestions??
