Make no assumptions about fluids that may or may not be in the car. At least inspect everything, if not change everything. Differential fluid, coolant, ATF, etc. Pretty easy, cheap way to get many parts of your car worked on.
I learned that lesson on the very first car I bought, 30+ years ago. I drove it for 3 months until the transmission (5-speed) stopped working. Turns out the gear oil had been drained and it was bone dry. I knew the guy who sold it to me, but he had drained it 1+year before selling it to me (it was a project car), and had forgotten about it so he did not warn me.

How long does a tune up take? 94 LS
I want to do a tune up on my car tomorrow and I'm wondering how long it should take someone like me who's done things like this before? I plan on doing cap, rotor, plugs, and wires. If I start at 8 am, I should be able to finish by the end of the day right?

Spark plugs and wires done
Got around to doing my plugs and wires this morning. Didn't have time to do a full write up, but that's what lexls.com is for. I decided not do my cap and rotor until I change out my timing belt since the car starts and idles just fine the way it is. The car runs great! Not sure if there is a definite power increase, but it does feel a little peppier. I also noticed that my spark plugs had the part number pk20r11 and the new ones i got had sk20r11. I tested all the wires, old and new. I found that the new wires were almost exactly half the resistance of the OEM wires. Im still keeping the OEM wires since they're still ok. I had my meter set to 40K ohms.
OEM Wires Resistance:
1 - 4.9
2 - 4.88
3 - 14.6
4 - 14.9
5 - 16
6 - 16.1
7 - 10.3
8 - 10.3
NGK Wires Resistance:
1 - 2.3
2 - 2.4
3 - 7.6
4 - 7.6
5 - 8
6 - 8.35
7 - 5.25
8 - 5.2
