Hi all,
Have a question for anyone with some similar experience. Car is a 1998 Legacy Outback, 2.5L, Auto trans, 113K miles. Timing belt was SUPPOSEDLY replaced at 90k(I'm not sure). No maintenance history available. The engine has some light vibration (not enough to spill your coffee, but noticeable) when idling, and this vibration / shaking increases noticably with rpm especially in the 1500 to 2500 rpm range. The vibration is not readily apparent while driving, though with snow tires on all fours it's somewhat difficult to tell. The car is also quite difficult to start when very cold - it kind of chuggs to life after prolonged cranking. I have read other threads here and on other BB's with the following answers:
1) Camshaft timing off
2) Injector fouled / fuel management problem
3) Ignition, plugs, wires, coil...
4) Head gasket leak
5) Short skirted piston design
6) Broken/bad motor mount
7) Some subbies simply vibrate and some don't (yeah, BUT WHY?)
Any help appreciated. I'm thinking of starting with ignition components, and perhaps moving towards the injectors / fuel system and then timing belt(properly positioned?
Thanks,
