ok a little history... put a flowmaster on the 4runner, later on my check engine lighjt came on, it was the catalyst error saying my cats were bad, so i cut the second one off, ran it, then unbolted the first cat and cleaned it out knowing thats not gonna make my engine light go off cause my o2 will then be getting a bad reading and so i havnt solved anything right? so i bout an o2 simulator in hopes of it sending my ecu a good reading and correct me if im wrong but if the computer get a bad reading then doesnt it adjust your motors air/fuel mixture? so in one day i put the simulator on changed my oil put some lucas fuel cleaner in a full tank of gas, 15 miles later engine light came on truck runs like crap, real rough at idle and i ran the code and its at system too lean bank 1.
any help would be greatly appreciated.
