Re: how to inspect distributor cap

Use the OEM AC-Delco plugs that the parts book calls for.
The cap and rotor the best thing is to take it off and look at it.
Check for moisture or cracks or corrision. Look at the end and base of rotor for carbon tracking and wear. Check the dist shaft for side play.
You did not say how many miles or what engine.
Plug wires is another main idem to check along with fuel and air filters.
And have a look at belts and hoses to. Check for lose of coolant and remember the coolant needs flushed and changed ever so often.
