When getting up to highway speed (beginning around 45mph) the car begins to shake and lose power. The check engine light comes on. Sometimes it will keep going an get past the issue and be fine, other times it will completely lose power and I have to pull over and start it again. I am no longer driving it on the highway. Several people have looked at it and no one can tell me what's wrong or how to fix it.

Thanks for the suggestion but there's been no problems with the anti-freeze or smoke. I've had three shops look at this car, two of which left the car with for several days. This is killing me!

Hi there,
I had the same problem with my 96 Legacy Wagon, and took it to several different mechanics over several years.  The car was losing power and seemingly going from 4 cylinders to 2 cylinders, and back.  No one could find the problem.  Finally took it to Superior Subaru in Burien, and they replaced the coil.  Fixed the problem!    Hi there, I had the same problem with my 96 Legacy Wagon, and took it to several different mechanics over several years.  The car was losing power and seemingly going from 4 cylinders to 2 cylinders, and back.  No one could find the problem.  Finally took it to Superior Subaru in Burien, and they replaced the coil.  Fixed the problem!
