So my car is almost to 75k miles, and I figure its time to do some maintenance that probably has not ever been done. Here is what I have come up with so far, if anyone has anything else I should add to my list, please say so.


When I change plugs, I want to go one step colder in case I decide on more boost in the future. What kind of plugs should I get?


Plugs and wires
Fuel filter
coolant flush and fill
trans filter/fluid
supercharger oil
Serpentine belt

 

Keane:
Looks like you pretty much have your bases covered...
Seeing how mines an N/A not sure what plugs would best fulfill that need.

Maybe even consider,
Replacing brake fluid
Replacing powersteering fluid..
Just for good measure.

 

It's probably a bit overwhelming, but take a gander at the thread below:

Keanne, your list is a great start. David has some good ideas too. BTW - If you are not up to bleeding brakes OR a Power Steering system, get a cheap (like dollar store) turkey baster. Suck out as much old PS and Brake fluid as you can. Top off with clean fluid. True, not a "flush" or replacement, but still an improvement.

I would definitely add changing the Supercharger oil (notes on that in the thread I linked above).

Clean the MAF with MAF cleaner (sure, doesn't need it, but doesn't hurt it either).

And inspect your belts to see if they need to be changed.

Outside of that, the thread I linked to has a wealth of other helpful ideas for this.

 

Forgot to add supercharger oil, I just did the MAF today as im having an idle/stall/hesitation problem and Mike said I should give that a try.

 

The TPS might need a good cleaning and re lube.

 

A few things were mentioned, so for now i'll do one thing at a time and see if anything makes difference.

 

Oxygen sensor was probably never changed on the car either.

That would be a good 75k thing to change.

 

One was just changed not long ago, had a check engine light for it. I believe it was the upstream one.

 

Oh okay, nevermind then. That's the important one.

 

Added serpentine belt to the list as it looks like its probably original. Mike, could you recommend a set of plugs if I were to go a step colder?
