There isn't much to a tuneup now days, I wouldn't even bother with plugs and wires unless it needed it. The basic tune up is an oil change, air filter, check all fluids, brake pads, hoses, any thing that needs attention. I don't think I have changed plugs in 10 years, or wires for that matter. And I am driving a 94. Hope this helps.

To get a tune up on m 95 cadillac deville what parts do I need.

I would start by getting spark plugs and spark plug wires. And find out (through part store)what the gap is for your plugs.Then i would replace the cap and rotor and check your air filter. If you have over 60,000 miles i would also change the trans.filter and fluid

Spark plugs
Spark plug wires
Distributer cap

Air Filter ?

That's a multiple cylinder misfire. Different auto parts stores charge different prices for plugs and plug wires, depending on the size of the engine, and you were to do it yourself, somewhere around $50.00 to a $100.00. If you were to have it done, over a $100.00.
