I need a mixture control valve for my 86 trooper. Found out that this is causing my major engine stalling and rough running. Capped off the lines now it stays running but still still runs rough and no power on the hwy. I am not gonna pay 150 through isuzu. Would love some help on this plz. Thanks!!!!
