Took my truckinto the local toyota dealership because my truck popped some codes they ran a test and said your catalytic converters are bad and all your sensors are bad quote was 4000 bucks
I said F that and had my bro take it home searched TW and fixed the problem for 25 bucks. Turns out is was a bad a/f relay in the main circuit breaker. Sounds like they ran the test saw I had the JBA headers welded on and basically didnt check the obvious I am very disappointed with them.
Just A day earlier I took it in they replaced my oil sending unit ran great then pops these codes cant believe they dont know how to do their job and TW does wow TW FTW
