Ok. I think I found the issue. This morning I took out the throttle valve actuator and noticed the pigtail that connects to it, doesn’t have a lock on it. So the last shop that just did transmission work to it either broke it or was already like that. But why put it back like that and not even...
So I cleaned this pigtail with electrical cleaner because there seems to be oil from my blow by tube. I added an extension so hopefully it doesn’t go on the plug again. Truck ran great coming to work this morning and ran fine going home.
At this point, I can only think of something electrical. When the truck runs great but as soon as the code comes on, its a whole different story. Has that hard shift from 2nd to 3rd and high rpm when shifting.
Here I am back again. Had my truck in the shop for 2 months (Nov/Dec 2022) now its april 2023. P1754 I’ve replaced everything I can think of. Spent over $7k on this issue past 5 years. At this point, just want to sell the truck.
