What is causing hesitation and shuddering on acceleration?

It could be many things. Does the engine misfire? When was the last tune up? Have you checked fuel pressure? Any vacuum leaks?

Replaced distributor cap, it's a little loose could that be a problem? The engine hasn't ever misfired. Last tune up today with spark plugs and plug wires. Last week oil filter changed due to oil drip. Checked for vacuum leaks; but not by professional. Put new fuel pressure gauge on last month. Any new thoughts?

How loose is the distributor cap? That shouldn't be loose.
