Improper tuning???

[QUOTE="Zeb, post: 1527476, member: 30304"] P1316 code comes from the high to low side open codes. High to low side open codes come from too much resistance in the circuit from the IDM to the injector. It could be in the harness, it could be in the uvch, it could be the injector solenoid, and it could be from improper clearance between the armature and solenoid when the injector fires. When you did the buzz test, did some of the injectors buzz quieter than the others? [/QUOTE]
