my car is pulling a code for both 02 sensors. it is saying they are hot. the car is missing some in high rpms sometimes and it seems to run rich. we have cleared the codes twice and they come on whenever the car is started up the second time. it still runs funny before the light comes on. i am guessing the o2 sensors are just bad. i have the mil eliminators on to cut off the light and it does have a bbk off road h pipe. does anybody think that a pair of o2 simulators might solve the problem or do i need to fork out the money for some 02 sensors? the car will run fine sometimes and sometimes it will miss.
