I've gone well over 100k now, about 111k at this moment. The past 4 months I have done everything I think I can do as far as preventative maintenance on the vehicle. Gotten plugs and wires replaced, coolant flush, replaced front break pads and rotors, changed out tranny fluid, brand new tires, oil changes religiously every 3k miles along with lucas oil stabilizer, and finally changing out the ignition coils tonight. Everything else I haven't mentioned is in great working order. So far the car runs great even prior to changing out the coils which have lasted me 60k miles so far. Everything in the car's suspension is in great shape as well.

My only concern is this, what are some problems with the car that sneak up on people associated with high miles that I have not considered yet??? I'm asking now so I won't have to pay big bucks later to fix a problem i could solve now.

 

fuel pump

 

The only problems that might crop up is you having a heart attack from obsessing over your car so much. Chill! Peace of mind is overrated.

 

Sensors...

 

bushings as they tend to get soft and tear over time and miles

 

just finished the ignition coils, no hiccups, went smoothly. bushings are good, i know that for sure. havent really thought about the fuel pump, the sensors eventually but i havent noticed any degrading performance in them.

 

111K miles? its about time for the sensors.

not even expensive for something that needs to be change every 50-100K or so.

and yes, do the fuel pump.

 

Also change your diff oil if you have not already done so.

 

Very impressive.

 

When you changed the coils did you find the metal baseplate they are bolted down to, was a bit rusty and pitted? If so, did you replace it or just cleaned it and if so, what did you used?

 

Which sensors ???

 

You missed out on ALL the hoses for cooling!

Brake fluid flush.. not bleeding.. flush

Soap, Clay bar, Soap then wax

 

The only thing you've forgotten to do is to blow up your 3rd engine by now and blame it on the type of oil you use!

 

Are you doing pre-mixing?
