ok, i know that when you get a downpipe a code will most likely come up for emissions, but i have been through hell and back with this down pipe/ o2 sensors. After installing it i got my codes checked and both my o2 sensors were bad... replaced them and now (about 2 weeks later) i still have 3 codes...

P0140 16524 035- o2 sensor circuit, Bank 1- sensor 2 No activity Detected

P1114 17522 035- bank 1, sensor 2 internal resistance too large

P1128 17536 035- bank 1, mixture adaption (multi) system too lean

i do have spark plug nonfoulers spacing it out from the down pipe, but they still come up with or without them on.......PLEASE HELP!!!

thanks alot

 

did you have the codes cleared from the last time you got scanned?

 

yes, i have them cleared every time.

 

Did yoy remove the catalytic converter?

 

yes i have a atp 3 in' dp

 

does anybody know why there would be no activity detected at all.... could it be a dud o2 sensor (its bosch)....or could the connection from the o2 to the computer be messed up??
