Earl needs B100
Will a bad injector pressure regulator valve cause such problems? Maybe loose nut on the IPR or loose connection?
It could but should also throw the P1211. I think my IPR vavle is getting weak, it idles down to low and has an uneven idle. But I get the P-1211 code at times also.roosterdiesel said:Will a bad injector pressure regulator valve cause such problems? Maybe loose nut on the IPR or loose connection?
