Wasted $44.
It might work for some people but it didn’t do anything for me but certainly might have improved things slightly or not hurt. But I saw no noticeable effects. But I do have 2 exhaust leaks. I fixed those exhaust leaks and still see no difference. This code popped up when I put in a livermois TUNE and MAP sensor.
When I revert back to stock and remove the sensor, the codes disappear. Livermois told me they suspect my cats are “going bad.” but I see no evidence of this besides the codes.
My 80 year old pro mechanic pops suggests that perhaps there isn’t anything wrong with the exhaust besides 2 leaks I found and that’s why cataclean did nothing for me. In other videos, all but one of the oxygen sensors have been replaced, and a camera inspection of the catalytic converters and temp and pressure test showed they are good.
