Had a 90s Lexus. Check engine light came on. I freaked, wondering what major repair Bill might come my way. Googled it, it was just my gas cap was not screwed and tightly after filling gas. Solve the problem I never had an issue again. Of any sort.
I used this SO MANY TIMES in the Blazers, and other cars. Dad showed me how to do that, seal a leak, 50 yrs ago, RIP Dad.
