What should be involved / have done or changed? Thanks in advance.

 

The service intervals are in the Owner's Manual (if you don't have one they are on line free).

There is no "tune up" for 75K,

At 50K severe service change the AT and TC fluids, otherwise it is 100K with the spark plug change.

Not in the manual at all is clean your Throttle Body (with Throttle Body Cleaner) and clean your MAF with .......... (MAF Cleaner). Should be done about every 50K, maybe more if you live in a very dusty area.

Drive on.

 

Thanks Doc.
