Hey guys im new to this but im gonna let u know what i just went through.
Ive been following this for a while till i got my car fixed 96 subaru 2.2l legacy.
Driving to work on the freeway 65mph it started bogging down lost speed backfire all that fun stuff.Checked the codes and it was a miss fire #2 cyl.
Took it to a mechanic he told me,Bad valve seat,Clogged cats (both),And had a oil leak from the front main seal.
So i dident have all the money to get all that fixed so i told him to fix the oil leak(new timing belt)and new front seal.
Got a phone call the next day a miracle happend My car was a tooth out of time and the front main seal was put in backwards.
Sorry for the spelling but i hope this helps!!!!
