Trying to tune up my 2003 ford explorer 6 cyl 4.0 xlt

Hey guys i am fairly new to this and probably this question has been asked before but i was wondering if anyone can help and explain to me how to do a full tune up to my car and what i need or should i just take it to the mechanic i am pretty good with fixing and doing things but i need some guidance. Thanx in advance. All the help is appreciated bc I am currently low on cash to take it to mechanics lol. Thanx again

Anyone

If you do a search in this forum you will find all the answers you are looking for but normally a tune up is replace Spark Plugs, Spark Plug wires, Fuel Filter, Air filter, New Oil and Filter, Maybe some fuel system cleaner and depending on the mileage checking/replacing differential, and transfer case fluid. If you really get into it you can also flush/replace radiator/coolant and transmission fluid and filter. Good Luck with your tune up

Thank you mad. Helps a lot

I recently did a tune-up on mine (02 Mountaineer AWD V6). The fuel filter is a b***h to get off. I finally gave up and brought it somewhere and paid $20 to have it replaced. I even had the correct tool to remove it and still couldn't get it disconnected. Other than that, everything else was pretty easy to do. I removed my fuel injectors and soaked them in Seafoam over night as opposed to using a fuel injector cleaner through the gas tank.

In addition, clean the idle air control valve, throttle body, and MAF sensor.
The MAF sensor can be safely cleaned without removing it from the housing.
