I had a low mileage 2.2 engine put in my 1999 Legacy Outback, with an original 2.5 engine after going through a head gasket job that brought up the compression to create new problems necessitating another engine. The problem here is I have not been able to pass emissions here in Connecticut. I brought it to J and J which has serviced this vehicle for the duration, but did not put in the used 2.2 engine; that was done by a Subaru repair facility in Lyndonville, VT.
We have already spent a lot of time trying to bring the car up to code with parts changing without getting the emissions to pass. Paul says it is an electrical short in the map sensor that would have to be trouble shooted.
Does anyone know if these problems are standard with 2.5 to 2.2 conversions and what is the usual successful path on this? Thanks.
