No you do not need to replace any plugs at all when replacing wires.
Changing the plugs and plug wires correctly has nothing to do with nor can it cause an oil leak.
No. However, newer plug wires can be extremely difficult to remove without damaging them.
Well start by changing your regular spark plugs with performance plugs and also change ur plug wires too, try performance plug wires. Get a after market cool air intake.

Spark plugs and wires

recheck wires to plugs sounds like two are crossed
If the old plugs and wires were bad I would expect the engine to start and run better.
first up i would check to make sure all plug wires are installed to the correct plugs 2 wires swapped to out of sequence plugs will cause this misfire
It depends on the condition of the wires currently in use. If they are cracked or frayed, by all means, replace them. start the moter at night or in the dark and wach for sparks betwen wires
i think you disconnect one of the plug wires or you need to change one of them . It could be the oxygen sensor, valves, plug wires or a sticking fuel injector. You'll have to get a little more specific. If it ran well BEFORE changing the plugs and now it doesn't, perhaps 2 of the plug wires have been cross-connected.
