help me on my 16804 problem guys

[50spence]

keep getting this code up 16804 . i clear it but after about 20 or so miles it goes in to limp mode again ,ive got the car de catted so im guessing its something to do with the amount of gasses passing through the sensor . ive tryed gapping the sensor a little but it aint making much difference . im not looking to get a remap just to solve the problem so eny valuable info would be verry much appreciated.

do you know if the post cat lambda sensor has been mapped out ? or have you just fitted the decat without doing this?

just fitted a stainless straight through

sounds like its detecting the exhaust emission values are too high and putting you in limp mode you either need to get it mapped out or try to relocate the lambda sensor so that is not in the direct flow of gasses
