In a week or two I will be doing a spring tune up on my car. The basic oil change, filters, and spark plugs/wires. I was looking for any ideas on what else I can do that is reasonable priced and in the easy to moderate difficulty range. I am not to much mechanically inclined, but with a good set of instructions I can figure something out.

I just did the free zzp mod where you improve your ground wire mounting. Except i added another wire (i think 8 gauge?) from the battery to the ground location in parallel and I also added another wire from the alternator to the battery in parallel. My voltage went up a little and i just used stereo power wire that i already had. so, 0 bills.

I assume you're doing o2 and fuel filter?

Maybe PCV for ***** and giggles.

Reset your PCM when you're done.

Nope, you assumed wrong. Are they easy to do, or where can I find some info on how to do it? I looked at o2 sensors but how the hell do i figure out if i need a back or front sensor? PCV is what exactly. Heard many times it talked about, but never really figured out what it was still. Like I said, anything that is basic and if I **** something up, I can fix it myself.

Oh yeah, you have two o2'*. The front is exposed to more gasses and heat, so do that one minimum. You install it just like a spark plug in the exaust manifold really. My 3 wire heated one was $35 or so, but yours are different.

The PCV is a valve that keeps the crankcase pressure normal. It allows the engine to "breathe" so to speak. They're like $5 and can mess you up some if they've gone bad.

Allright, I will look into that. Thanks!

The o2 sensor is as easy as a spark plug to change out, 22mm wrench is all you need.
When was the last time you rotated the tires? Cheap to do and adds miles to your treads
Rad flush and new coolant, not to pricey and good insurance. Hows your accessory belt? check for cracks or worn condition replace as needed, keep the old in the trunk 'just in case'.

transmission flush, have you read the thread about GM'* Top Engine Cleaner? (do a search for Holy Smokes) PCV is to the left of your upper intake manifold. fuel filter maybe, but that can be messy. check the battery to make sure its got enough distilled water in the top. Check the back of your manual, it might have some stuff we missed.

Ill look into the sensors and think about that engine cleaner

i would suggest the pcv valve it let'* your engine breathe and in turn let'* pressure off your internal parts also if it goes bad it cause leaks around gaskets. if there is no pressure releif the pressure pushes on your gaskets and can cause them to leak, mainly your front and rear main seals. i change mine every 6 months and check it at every oil change. check it by removing it and shaking it if you hear the rattle inside it is good if you don't hear a rattle inside of it then change it.
