It is not.
Just wait until the CEL flashes on. I think these sensors last 150K miles and longer...and this is an unscientific guess..

If your mileage drops off then it may be time. They usually degrade slowly over time until the computer says "enough" and gives you the CEL.

I just replaced mine (about a month ago) with 185,000 miles on the original. No CEL, just figured it was time. MPG around town went from 21.7 to 29.6 (as of today). Part of the bad around town mileage was from the big-@ $ $ hole in the IAC hose when I was going WOT all the time to get some decent boost. Some of the mileage increase is also attributable to going full 3" exhaust from turbo back (where before it was only 3" to the flex pipe).

That's a huge increase in MPG. I usually get around 21mpg in town and 27mpg highway, and I am light on the throttle.

I am just going to change it since it's cheap and I only have one in my '94.

I got my second (as a spare) on e-bay, new, for $46.00 shipped. Original fit - no splicing.

Here is one (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&backtolistreferer=http%3A%2F%2Fmy.ebay.com%2Fws%2F eBayISAPI.dll%3FMyEbayBeta&item=290270850569&viewitem=) for the same starting bid ($39.95) but a different seller. I bid $41.00 and no one else bid. With shipping, it came to just under $46.00.
