Anyone run a fuel injector cleaner like something like techron (the ones that contain PEA) and got a check engine light? I picked up a 2006 mazda3 with the 2.3L and has about 95,000 miles on it. decided to run a tank of techron and got a check engine light half way thru. not sure if its related but was just curious. i dont have a scanner rn so i cant check but will in the next few days.
I assume maybe a piece of gunk or carbon that broke off hit an o2 sensor or something or maybe the fuel system doesnt like the cleaner or something.
