New within the year to Volvo ownership...Love this SUV...I have an OBD2 code reader...I guess these vehicles have major "techy" systems and need special tools to do alot of the work...correct me if I am wrong..I have a check engine light on..Car started acting crazy a couple days after light came on..Symptoms: stalling, misfiring, chugging..I found out that my daughter put a full tank of 87 octane in the tank...could this maybe have started the fuel pressure sensor issue? I had a mechanic change the fuel filter..light is still coming on within 1 driving cycle...It was intermittent at first..Before the full tank of 87..Now comes on and stays on... Can I bleed the fuel system pressure by taking out the fuel pump fuse and letting the engine run out of gas? If so then is this part change out straight forward? How can I bleed the system properly without a special connection and pump.. Not sure if I should post this here but sorry..
Thanks
Thanks
