so yesterday i was drivin and my car just started messin up anytime i reved over 2000 rpm's i lost all power until it got under 2000 again, i check my timing belt its not that and im gettin a cel code of po141 which is an o2 sensor heater malfunction (bank 1 sensor 2)..... how exactly do i go about fixing this, and does anyone have any idea if this will solve my problem?

 

be more specific... messing up how? i cant see a connection between the symptom and the CEL the way ur describing it

 

im pretty sure my car just went into limp mode cause my o2 sensor went bad but when im drivin the car looses power at 2000 rpms....still drives but looses a lot of power

 

fixed the problem i had a bad o2 sensor and my spark plugs were gapped wrong
