My car is idling and running like ****. I have no cels. Its on my 92 hatch with b16a. Could a bad 02 sensor causing erratic rough idling and rich running? Please help.,

Mike

 

rough idle, hesitation when accelerating, burning excessive fuel, and of course a cel.(sometimes a cel)

 

someone just told me that you cant run aftermarket headers on hondas bc it flows too much and the 02 sensor can't work with them. is this true?>

 

You can run aftermarket headers on a Honda and the O2 sensors will still work.

I had a bad O2 and i didn't get a code for it either! I did a mini-me on my y7 in my 98 lx, and i was running lean as hell, my a/f gauge stayed on the lean side no matter what! And I did a search, talked to some good mechanics, and they told me to change the ecu cuz the fuel map is different for the vtec head!!! well I did and it didn't solve the problem. I tested my O2 like 100 times and it checked out good. So a month later I said expletive it and ordered a used O2 sensor from HAP and BAM fixed the prob!!! It was weird, becasue these OBD2 ecus are crazy with throwing codes, but it didn't throw one for my o2 in this situation!!!
