Ok I bought a 2007 subaru wrx limited at a car auction thinking I got a good deal but I can't seem to get it started, so im not sure now. its my first subaru so I dont know much about them. I tried to start the car and it turned over but would not run. so what I did is changed all the spark plugs an that did nothing. so I checked if the coils were working and it seems that the coils on the passenger side are not working but the ones on the drivers side seem to work just fine. so I thought maybe its the coils so I switched them around and they work just fine on the other side. now I dont know what to do can anyone help me?
