I have a 2008 Subaru Impreza Outback Sport with 94k miles (have always done oil change, 30k and 60k service on time). The check engine light started to blink while I was driving. Within .5 mile, I was dead in the water. I towed it to my Subaru dealership and they said the sparkplugs (100k mile life expentancy) failed which caused the coils and spark plug seals to break. After they performed the work, the car still will not run. The speculate that its the right cylinder head that needs to be replaced but will have to charge $700 just to diagnose the problem. What do you think is going on? It sounds like we have a similar. Thanks.
Note: I know little about cars so I'm desparately seeking advise.
