Question about 2007 Volvo XC90 V8 AWD Sport
Just like with auto electrics,always check the grounds.Only with this situation,check the EGR valve.Find it on the intake with vacuum hoses hooked to it.There is a small opening/hole in the top side of the EGR(exhaust gas recirculation valve),wit engine running,use the eraser end of a pincil and push down lightly on the diaphram inside.If engine speed changes,it's good.If engine speed does not change,replace the EGR.You have a hard time climbing a grade if it's bad.Regards,Rigger
