don't know how you have been doing your maintenence....
with my vehicle the drive train fluids are all replaced every 30-40,ooomi...this includes front rear diff , tranfercase, and the transmission filter...the transmission fluid is now called dexronVI,,this replaced the dexron III that damages these transmissions..this was a service bulletin that GM set to the dealerships.
the coolant is replaced every 3-4 years dexcool @60% with distilled water...
the plugs need replacement @ 50,ooomi...thats all there good for...replace with the newer plug GM now recommends..
the air filter should be replaced every 15,ooomi or sooner
the IAC/THROTTLE BODY/MAF needs cleaning every 50,ooomi,,,
plug wires need inspection/resistance check,,,If original and resistance is higher than spec. replace at this time...
the upstream O2 sensors need replacing at the 100,ooomi mark,,,especially if you do a lot of stop/go traffic driving...these sensors usually throw a service engine light very quickly when they go out of range,,but the cat converter can get damaged if they don't work correctly and these converter are expensive..
the brake fluid should be given a good bleed to replace most of the fluid with new...this if done properly would need equiptment that cycles the ABS valves..
check and lube all front end componets ,,
I'm sure others have items that would be a good way to avoid problems..
