those can beat you to crap doing every kind of problems example in my case first the idle was irregular then there was a lot of crap they make that no fuel come to half the engine then changed it of place and then too much fuel were coming to the cylinders so the result no explosion and the computer almost to commit suicide i see the numbers in the scanner and they were extreme and irregular the computer can get crazy whit just one bad oxygen sensor...
so a tip if you are reaching or past the 100k miles on your engine change them before it makes you get crazy
