have a 97 subaru Impreza with 173,000 miles. Never a problem until Christmas Day 05--started shaking like it has a flat tire. No flat tire. Had tires replaced. Still happens. Switched front and rear tires. Still happens. Noticed it happens on accelleration only. Seems related problems happened since then--loss of power and stalling--Idle control valve replaced and Air intake valve--runs nice again. Still vibrates on accelleration. I am concerned that if I continue driving, the very costly repairs I just had done will need to be done again. What should I have checked? Is my car worth keeping? No one seems to have heard of this problem.
Can someone other than a dealer deal with this? Can I use used parts instead of brand new shiny parts that cost a lot of money?

Check the U-joints on the drive axels. Also check broken motor mounts.

Check the U-joints on the drive axles and inspect the motor mounts for breakage.

Conversation Summary

A 1997 Subaru Impreza with 173,000 miles began shaking like a flat tire, only during acceleration, after Christmas 2005. Tires were replaced and front and rear tires were swapped, but the vibration continued. An idle control valve and air intake valve were later replaced, which restored power and idle, but the acceleration vibration remained. The owner asked what to check, whether the car was worth keeping, and whether a non-dealer shop or used parts could be used. The expert advised checking the drive-axle U-joints and looking for broken motor mounts. The owner planned to have that done.
