Still havent gotten to drive the thing yet, ive been temporarily driving another vehicle , and with work and my current situation, its hard to make time, and i havent wanted to take another gamble and have it fall apart on me while going to my destination.
...but ive been revving it up and letting it run here for 10 minutes,
No tach bouncing, no misfiring, and no breaking up at 3000 , no matter the throttle position. Also it goes beyond 4500 which is interesting. I recall once upon a time it kinda fell on its ass at 4500. Not that it makes much power there.
This DEFINITELY made a change of the trucks.operatiom because everything ive done thus far showed me i was fixing the WRONG thing after the truck had ran for 5 minutes. It'd go back to jumping around, stalling, misfiring, bouncing the tach, etc
Let this be a lesson for all future TBI readers, a functional ICM isnt a good ICM !!!
