O2 sensor help

[kon15]

ok my check engine light came on so i checked out why and it was saying that my O2 sensor was malfunctioning with high voltage and with low voltage can anyone help me with this

Hey Kon15, do you have a custom intake on the truck??

[kon15]

yeah i do have on why? i have a brute force on there..........i also have a flomaster 50 series 1 in 2 out on it too idk if that will make a difference but im thinking that the computer might not be reading it right becasue of all the new stuff on it taking in more air and letting more air out

My SES keeps coming on and off randomly and this was before the muffler swap. Not sure if it was this forum or another to check out the MAF sensor and clean it. It just comes on less often now.

[kon15]

yeah and i just ran over a damn peice of steel in my new tires

[BizzareCustoms]

could be a bad sensor. Mine has a k&n intake a flowmaster 1 in 2 out and i dont have any problems but i have seen intakes cause random codes before. easy check would be to put the stock intake on if you still have it

what is the code? these trucks are very accepting of exhausts and intakes

[kon15]

ok so this is now the thrid time my truck has blown the bank 1 O2 sensor in less than 3 years

get a short spark plug anti foul spacer and space the O2 out from the exhaust path - Running this setup on my daily to get through emissions with a bad cat :D
