I have a naturally aspirated 3800 series 2 engine.
it has an issue where it is skipping when under heavy load such as running at slower speed in overdrive.
it has a new upper intake manifold, lower intake manifold gaskets, plugs and wires.
the check engine light is off and aside from the skip it runs smoother.
if I run it long enough the skip seems to go away but it has to have been running for a long time.
it is not losing antifreeze or oil.
any idea where I can start? It has the OBD 1.5 computer in it, old OBD1 with OBD 2 plug.
have the same problem?
