Clean Throttle Body, Clean MAF, Change air-filter if needed (manual recommends every two years unless you live in a dusty environment), change fuel filter ( depending on mileage or time. I do mine every two or three years, if it has never been done, do it). Run a good injector cleaner through (Chevron Techron if you can find it)the fuel system, then run another tank of gas through, and then do an oil change with synthetic oil and a good quality oil filter (Wix are good (napa) or any of the OE/OEM German filters like mann, mahle or bosch.).
Pros: good quality oil filter
Vehicle:
