I like to think things are easier these days. Some might not agree, but read on.
You used to tune a carb and set timing. There'* no intervention for fuel air and timing until you start modding and messing around. Meanwhile the computer automatically hooks you up. You clean the throttle body like you would the outside of a carb. Hardly any disassembly, no springs or little things to fly out when the carb comes apart.
Timing.. the coils and computer do it all. Once you hook them up, you'll never be 180 degrees or a couple of teeth off. If you got the plug wires right..you are firing.
Sure there'* a couple more sensors and a few different cleaners, but overall our 3.8L'* are still a nice and simple pushrod motor just like the 60'*-80'*.
A can of TB cleaner and a toothbrush will take care of your throttle body cleaning, seafoam..ehhhh if you want to, probably could use plugs and wires. Beyond that..get the trans service done or pull out some fluid to get it to the right level. All automatic transmissions that I've worked with are check when running. The hot/cold thing isn't as big of a deal, but the running part is.
Something that may help out is to take a read through the owners manual. It'* a wealth of knowledge about the basics of the car.
