My 2000 5.7 vortec started running poorly. The symptoms are as follows.
Out of gear I can rev up and it sounds fine. When I go into gear it runs fine up to 2000 RPM. If I bump the throttle up at 2000 rpm it bogs down and misfires. If I push the throttle fast through 2000 rpm it gets up and going but sounds and feels like it is running on 7 cylinders. I have no oil in water or water in oil and fuel filters are all clean.

Spark plugs look good and plug wires have no cuts or burn marks.
Can you give me an idea of what to look for?
