Answer 1

I own a shop, and what we do is this. We replace air & fuel filters, PVC valve, and plugs & wires. If it's one that uses a cap & rotor, we do that too. We remove the hose from the snorkle, and give the throttle body a good cleaning with throttle body spray cleaner. We look the whole engine, transmission, and differential over for leaks, and tighten any, and all bolts, nuts, and screws that may need to be, in order to stop any leaks from gaskets that are getting settled down. We replace the belts, and any part of the belt system that need be, such as plastic pullies that wear down with flat spots on them. We use an air hose to blow the engine clean from excessive dirt & dust, and pay close attention to the alternator as the dust from the brushes inside them cause them to put out less power than they should. We clean the battery cables, and add some grease to keep them from corroding. We check all grounds that go from the battery to the body/engine, and ground straps that go from the engine to the body and/or the frame. We clean them, and add grease to keep it from rusting or corroding. We inspect every vacuum hose on the engine, and transmission for cracks, splits (where they plug on), soft, or anything that even looks like it could leak. We test the fuel pressure, and return line for any restrictions, plus we even replace the gas cap if the seal shows signs of wear or leakage. We check all fluid levels, engine, transmission, differential, coolant, brakes, power steering, and windshield washer. We inspect the wipers for wear & tear. We clean the top of the battery to stop surface drainage to ground. We blow the radiator, and AC unit clean with a air hose, and wash it out if we have to. We inspect for any loose wires, bad wires, or any that show signs of overheating. We check CV Joints for wear & tear, and all u-joints for needing greased. We blow the brake dust away from the wheel sensors so they continue to operate properly. We measure the tread depth on the tires for any unusual wear, and check the spare tire to make sure it has air in it, and give the lights a quick going over for any that are blown. I don't have my list handy, but we do a 156 point tune up that takes a while to do, and we advise the customer of any, and all things that may give them trouble down the road. This also helps our customer base, and we try to make that extra buck from stuff if they want it done too. We try to look out for our regular customers, and keep them happy and safe. If you do this yourself, you will find you can save yourself a lot of money in the long run, by taking care of anything that needs it now, rather than getting 100 miles down the road, and finding out the hard way.
A tune up isn't what it used to be, but it is well worth the effort.
Part 2:
I'm sure a lot of this does NOT apply to your vehicle, but do take all into consideration. In other words, if one is going to do a basic tune up, the best thing to do is what your owners manual suggests. Platinum spark plugs are ok, but "not reccomended" for all applications, and this is "important" to use the plugs that are used by the manufacture. With all the research and development the manufactures do, I'm sure they know what is best for your vehicle. Modern vehicles, still use old school internal combustion engines, but don't have a distributor in them. As far as the PCV valve goes "ALL" engines has these or they would sling the oil out of them. They "are" in fact servicable by removing and washing clean, and replacing them. Spark Plugs last longer, and the engine is managed by a computer, but using your common sense by following the manufactures reccomendations in the owners manual will keep you way ahead of the game.
Glad to help out, Good Luck!!!

Answer 2

I can see from other answers that most people don't know anything about modern cars.
Your Trailblazer:
Does not have a distrubutor cap rotor, or plug wires.
Has Platinum tipped spark plugs good for 100000 miles
Does not have a servicable PCV valve.

So with that said your tuneup would be to:
Replace the air filter element
Replace the fuel filter located above the metal shield under the fuel tank
Replace the wiper inserts
Change the engine oil and filter- reset the oil life monitor

Answer 3

Yes it is suppose to drip water when the A/C is used and its usual a lot of water. The foul odor is mold and comes from standing water in the case that hold the Heat and A/C so you can get hot air or cold air from the same vents. If the vehicle is less than 18000 miles on it then you may have a Lemon Complaint, call a good Lemon Law Attorney for some advise it usually don't cost you.

Answer 4

spark plug wires, rotar cap, pcv valve, airfilter and gas filter and maybe rotar button
