Problem: low rpm bucking, especially when cold. Stalling at red lights (restarts like a charm). Got codes 55 and 64 once, erased them and they never came back. Also experienced a strange knocking/rattling noise, which went away on its own.

-Electrically tested the injectors, hot. Got between 17.3 and 17.9 ohms everywhere.
-Spark plugs changed.
-Fuel pumps removed, visual inspection done: nothing was wrong.
-Fuel pressure tested. Idle: 41 psi, FP1: 46 psi, FP2: 48 psi.
-Fuel filter changed.

Receiving two NGK NTK o2 sensors tomorrow.
I was curious as to what mods may have been done prior to all this.
