Hello! Thank you so much for responding. That’s more or less what the mechanics said - what concerned me was that the check engine lights came on after I spent $853 at that mechanic the week before for a 100,000 mile tune up plus oil change. I wasn’t sure if I was getting ripped off cuz I’m a woman - it happens!!
Do you think I can wait until my next oil change due in May/June? I just don’t have the money to spend on it if isn’t urgent after all that I dropped last month. I don’t want to spend more than the car is actually worth 
Thank you again for taking your time to address this questions.
