Have tried a ecu reset ?

 

nope, is that some thing i can try at home?

 

possibly idle control valve

First try checking for a fault code: Scoobypedia | Trusted knowledge for everything Subaru | Knowledge / Reading ECU Fault Codes

To reset: Scoobypedia | Trusted knowledge for everything Subaru | Knowledge / ECU Reset
