Service Engine Soon Light…WAIT!
Today while driving back to work that stupid useless "service engine soon light" came on on my dashboard. I was sitting a red light so I turned off the A/C, turned down the radio and listened...everything sounded fine. The car was driving ok and there wasn't steam or anything pouring out of it. I didn't smell anythign odd either. So I drove on back to work and googled, "Why did my service engine soon light come on?"
I found this great article from Life Hacker .com that listed the 5 most common reasons that that light would come on. I just had a new air filter put on the last time I got my oil changed so I know that's not it. My catalytic converter has not failed after 65,000 miles and I think I'd have noticed something if it were the spark plugs. SO before I leave work today I'm going to check the gas cap and then when I get home see if I can find any info about the oxygen sensor.
My point in posting all this is that I'm doing all of these things before I take it to the shop. We know they'll just run a diagnostic and charge us money for that and then probably replace an oxygen sensor. I can go by the auto parts store tomorrow if I need to to get a diagnostic test done for way cheaper.
DON'T just rush to the auto shop if you don't need to. Sometimes, yes, it's necessary. Maybe this time it isn't!
