Welp, it was a good experience, speedy turn around, and my service guy, Kyle, at Toyota was very friendly and a total rockstar.
Now, I don’t know what a mass airflow sensor is, but apparently it can leave you stranded on the freeway if you break one. And it’s a fairly pricey bit of technology.
But if this fixes my “check engine” light issue and it’s my only serious issue with my ’02 4Runner since I got it in 2004, it’s all good in my book. :)
Now where can I set up my lemonade stand to recoup the costs… Hmmm.
