Define "tune-up"

Routine engine tune-up for an 07 SR5 2WD crewcab with 4.7L should include...(please complete/finish the sentence)

Truck runs well. Slyfox bypass kit installed. Almost exclusively driven around town, less than 100 miles per week. No towing/hauling. It's a Grandpa ride. MPGs are averaging 13-14 according to the Info readout. 87 octane fuel at fill ups. Odometer reads 175K.
Thanks in advance.

 

All fluids, filters, spark plug, clean out the throttle body and MAF. I'd probably throw some seafoam or injector cleaner in the gas. Grease all the driveshaft zerks. Check brake pads? That's everything I would do and consider a "tune up".

 

I have a very similar truck. Same year, engine, DC and 2wd if you don’t know the maintenance records I would assume nothing has been done you can run the VIN on Toyota.com any records will come up with any service that was performed by a dealer or Toyota approved garage

@ 175k miles I would be most concerned if the timing belt and water pump has been done, spark plugs would be 2nd

 

Addendum: spark plugs new about a year ago, water pump, timing & serpentine belts have also been replaced.

 

Than I would replace fluids. Rear Diff, Coolant, ATF and power steering

ATF a drain and fill which is 3-4 qts depending on how much there was in your begin with

Cooalant you could just do a drain and fill on the radiater or a flush involving deionized water and new coolant

Power Steering fluid would be a flush

Rear Differential would be a simple drain and fill similar to an engine oil change but without the filter

 

Local T dealer wants just under $800 for spark plug change & intake gasket, plus "pro" throttle body cleaning.
Spent less than $20 on CRC MAF cleaner (small can) & large can of Berrymans carb/choke/throttle body cleaner. That's Monday's chore...film at 11.
Gas Buddy & Fuelly sites accept 13-14 mpg as acceptable normal mpg for this truck as equipped & driven...Ave mpg.

 

One, and done. Took about 35 mins, because I'm a klutz and prone to drop tools. Pulled the MAF & cleaned w/CRC MAF sensor cleaner, let it evaporate & dry for about 10 mins. During which I pulled the intake hose at both ends & removed the top plastic cover. Left the TB in place & cleaned outside & inside using thin, lint-free white cotton rag and me digits...Berryman's B-12 Chemtool carb, choke & TB spray cleaner. It was black & cruddy inside but not too bad. Took two swipes all around inside & out to come clean. Idle went to about 1100 rpm after start & settled in/down to 750 rpm within 3 mins.
