Question: Hi, does anyone know the exact resistance (in ohms) my TBI fuel injectors should read when tested wi

(Notes: Dies upon starting, have to drive 2-footed or dies, hesitates, loss of power when accelerating from stoplights, can't run it over 30 miles per hour. Strange though, many times when unhooking/re-hooking battery to reset computer, truck runs great for approx. 30 mins, then reverts back to same bad performance. Have changed fuel pump, Idle Air Control, EGR Valve, Coolant Sensor, ECM - problem still there.)
