Okay guys, so I just want to get a couple of things understood...
I have two engines that came with my truck, both are 4d55t engines however, one has the waste-gated turbo setup and one does not. My truck is a 1985, what was correct for that year? I have tried to find the answer, but I have seen 1985's with both setups.
The other question is this: On my injection pump my fast idle is cable operated and I have another injection pump that has the same bracket setup, but almost every other pickup I have seen has what looks like a vacuum operated fast idle?
Can someone set me straight on this?
