It's a 350 vortec I replaced injector spider and doin the same thing idles high and when I first start the truck it starts right up when I shut it off and try to restart it it just cranks until I hold the throttle wide open. It's like it glides it self or sum thin any suggestions
Ohm check ECT also check terminal and wiring can leak coolant into wire. Ohms should be high cold and drop pff as warmed. If ohms stay high say 9K or higher then ECM gets cold engine signal and will rich fuel mix causing p[roblem
