Considering that its good to change the fuel filter every 10,000-15,000 miles just because they are so damn cheap and easy to change.....I think at 145,000 miles...you're ready

Idle Air Control (IAC)

Spray the **** outta the MAF with MAF cleaner.

But dude....I think its the filter. I would do that first, it'll take you 5 minutes to change and its like $15.00.

Then mess with the injectors.
