BESIDES OIL CHANGES, WHICH I GET ON SCHEDULE, WHAT SHOULD BE DONE AND HOW OFTEN WITH MY VEHICLE TO KEEP IT IN GREAT DRIVING CONDITION FOR YEARS?

It depends on how many miles you drive annually, the environment your vehicle is driven in (dusty, hot, cold, humid, dry, etc), the type of oil you use (conventional, synthetic blend, or full synthetic), and the condition of your car's engine. You should consult your owner's manual and the data on your engine oil.

I drive a 1999 Mercury Mountaineer 5,0L and drive it about 1,500 miles annually. I use a synthetic blend oil and change my oil and oil filter twice a year. I change the oil in the spring so I have fresh oil for the hot summer driving season and I change my truck's oil in the fall after the hot summer driving season. Because my Mountaineer has a lot of miles on it, I use thinner oil in the winter 5/20 and thicker oil in the summer 10/20. I check my oil regularly and look at the color and feel the oil for grit. This has worked for me for many years and I have had good performance from my vehicles.

You can go on the different oil manufacture's websites and read their recommendations as well. There has been much debate about when to change the oil in a vehicle so you have to decide for yourself what schedule you want to follow.

A vehicle & motor might help some

We'll guess

EGR Valve
Cylinder Misfires

Not as likely ---a failing fuel pump on the
stall out part or Idle Air Solenoid

That should keep you busy for a week or so

I would have to see it to say for sure.
Things like the timing belt and water pump should have been changed at every 80,000 mile point. Same goes for belts and coolant hoses.
Ignition system parts and the fuel filter around 60,000 mile points.
60k - 120k - 180k etc
Everything else is generally fix it when it breaks.
Most import engines and cars are expected to last 200,000 miles. So you are close to that mark but no reason to expect it to fall apart any time soon.

At that mileage it could be a lot of things. Being that it didn't stay on the problem is minor and not happening constantly. I would suggest spark plugs, fuel filter, and oxygen sensors. These components can be the cause of several check engine lights. Good luck.

just do your oil changes spark plug changes airfilters ,fuel filter, maybe a radiator flush to keep antifreeze fresh..check ur fluids brake,powersteering,just check tranny oil. do not do transmission oil change unless you have shifting problem people tend to change things that arent necessary i believe you having timming chain never has to be replaced just change things that you havent done since you've gotten it and you should be okay

The maintenance schedule is an outline and should be followed if you want to keep your vehicle in good condition. the maintenance items listed in the schedule are performed at their set intervals for a reason. Manufacturers have found the wear limits on certain parts and those parts may need to be serviced or replaced at those intervals or catastrophic failures may result.

It is good for your engine.

You have a good maintenance culture.

Cheers and rate this.

New timing belt and serpentine belt every 50,000 miles. New filter with every oil change. Replace the air filter when it gets so that you can't see diffuse light through it. Watch fluid levels. Have the CV joints and rubber boots checked every 20,000 miles or so. Check with your transmission servicer for fluid and filter changes. Replace platinum spark plugs every 100,000 miles along with new spark plug wiring. Check the codes if the check engine light comes on. Replace the fuel filter ever 20,000 miles--more often if poor fuel quality.
