General Questions

My '96 240 is hit 80k miles, I have recently within the past month replaced the fuel filter, and with the past year replaced the spark plugs.  

what else do I need to do or change keep the car running great.  What do I need to check into.

First I would do a major tuneup and replace stuff like:

air filter
pcv valve
cap
rotor
fuel filter
plugs
inspect and perhaps replace wires
replace o2 sensor
drain and flush cooling system (replace thermostat while your at it and check water pump for free play and noise)

check your brake rotors and pads
adjust idle
clean sensor connectors

This may seem like overkill, but I am very anal about maintenance...

Thanks for the help, man.  I have a lot of work to do I guess.  The weather is starting the warm up, so I will be able to start getting things done.
