2009 Forester SOHC 2.5 engine   automatic 
  
  
I was trying to do the 105,000 service on my car this weekend--new timing belt, pulleys, etc...  I have 116,000 miles. 
  
All was going well, until i screwed up.  I was removing the drivers side cam pulley to access the piece behind it so I could remove/replace the water pump.  (yes, the 2009 has a plastic plate that gets in the way of the water pump--early models do not have.) 
My helper was holding the drivers side cam with a cam pulley holder tool, but let it slip as I tried to remove the bolt.   The cam was turned to the left--the wrong direction--about to the 10 oclock position from the verticle it should have been. 
  
I got everything lined back up properly.  the timing marks on the crank and both cams all line up properly when I hand rotate the crank after the new belt was installed.    it all looks great --except for the fact that the car does not run well now..    the timing is screwed up., or something more sinister.  I am afraid to ask. 
  
I am stuck.  I was told if I go back in, remove the timing belt and hand rotate the drivers side cam a full rotation it would get everything back lined up and it may solve my problem.  
  
I need thoughts.   I need this car and cannot afford to take it to a repair shop. 
  
  
Thanks for your input
