Did u replace the intake manifold gasket between the upper and lower manifilolds? If so u may have left the spacer in the gasket which some didn’t need. That leaves an 1/8th inch gap between the two and the truck will barely run. I made that mistake when I did my head gaskets. Also make sure the timing is correct and all timing components are installed properly and everything is 100% put back together

How was it running before you worked on it?
In other words why did you do anything to it?
