Body will probably rust off before the thing stops running... just what I've heard from others...
What year? Could be just getting up to speed, or ready to drop dead... need more info...
My brother has a 22R with 300,000 or so... has had it for 21 years. He could change a clutch and timing chain with his eyes closed, and AutoZone hates that they sold him "lifetime" anything.
Best of luck.
