ive seen those roadside testing sites for smog out here in socal. well today i got stopped and all they did was plug into my computer inside the cab by your feet.
first off i am under the assumption that 1st gen tacomas have two cats. 1 front and 1 rear. now do you need an o2 simulator if you remove the rear cat? i plan on removing the rear in the future and adding a magnaflow 14 inch muffler.
now if you need an o2 simulator will you still pass smog if all they do is plug into your cars computer?
