Go to Auto Zone and they’ll use their diagnostic tester to see what’s up

I gave my husband a Car MD one Christmas when they were an advertiser on Frank Johnston and it’s been very helpful, but Auto Zone will do the same thing. Look. You’ve got an emergency fund. This is what this thing is for. Be thankful! You’ve got a potential problem and you’ve saved the money in an emergency fund to cover it. Believe me, every single one of us here will tell you as soon as you get an emergency fund, Murphy will follow. It’s just part of the program. That money will always need to be replenished but that’s ok. You’ve saved the money, and you can take care of the problem. No worries!

Around here we have auto zones

and if you ask they have one of those meters that they will come out and hook up to your vehicle and get the code and tell you what it says is wrong and will even print out directions from the computer for repair if you would like and do it all for free! I have used this more than once which makes it easier to decide if it is a “I can do it thing” or a shop here I come thing.
