Is your 4runner running ok meaning is there any problems with starting and in it's driving?

I have found many time these little check engine lights seem to just pop up and i feel it's mostly really nothing, just get a small code scanner i bought one at Walmart cost $19 and i remove the codes, every time my gas cap is not seated tight and those click click click things don't make me feel it's getting seated well.

The check engine light comes on also the anti skid light flashs, this is something Toyota has programmed to send people to their Toyota stealer dealer what does a un tight gas cap have to do with my anti skid system.

Auto Zone has cost more drivers more unneeded money, sure they scan for free and they always find codes to have you replace many unneeded parts.

If you remove the check engine lights codes, and your 4runner is working ok keep on trucking and save your money for something it really is needed.
