Check to see if there is gas at the exhaust or if it smells like too much gas. If there isn't any spark, then the fuel will not get burnt and will be expelled out the exhaust valve and into the exhaust system.There are several ways to check if you're getting spark. One way is taking it out and checking if it fires, but I don't have much experience there. What were the symptoms before the tune-up?

I think it should be driven more. Parents only take it out about one a month or even longer. Before tune up was running great About two weeks ago less then a mile from home started to run like hell they got it home. Next day I stared it and it I knew it was a bad plug so when I checked first plug it was full of oil. Tryed to check for spark the old fashioned way buy taking it out and starting car for a second to check for spark did not see any "but not to sure about how well that went I'm not at all formiluar with the coil packs". But could see needed new plugs.

The plug was oiled (the electrode end in the bore) or the plug recess in the cylinder head was full of oil?
If it's oiled, there's a problem with the cylinder bore/piston rings allowing oil 'blow by'.
Oil in the recess is a regular issue usually caused by failed camshaft cover rubber gasket or 'O' rings. Less often it is the result of a cracker cover. This does cause misfiring when the oil reached the coil pack.

I've deleted a number of your posts on this same topic from other forums. Do NOT multiple post the same question. This is the correct place for technical questions about your model.

Just to be clear for you:
- If there is oil on top of the sparkplug, it is most likely caused by leaking sparkplug seals, allowing oil dripping in the hole.
Fairly common problem on our cars, and can be solved by replacing the various seals after lifting the covers.
Seen various cars soaked in oil, but not seen major problems caused by that.
- If the oil however is on the sparkplug nose, that's an other story ...
If you say a fouled plug, I should suspect a faulty ignition coil, which should show up as a code.
Just move the faulty coil over to an other cylinder, and see if the fault follows for confirmation.
