alright here is an O2 question for you guys, I changed all my sensors, all except bank at the cat were nissan sensors, that last one is a bosch, so my car still is running shitty so I take it to nissan, I changed all of them my self, so they tell me that the bank one on the header is bad, and say they want like 200 to change it and its an hour and a half labor, I said f that I did it and the car was fine the light went off, but a week later it goes back on says that sensor is bad again but it was running fine, so i erased the code. no problems for 2 weeks now, then the code is thrown again and 2 days later turns off, the idle randomly drops but my a/f says Im at like 14.7 so I dont get it any advice

 

Next time it throws a code, it would be helpful for us to know what it is... You might also want to scan your ecu for any 'pending' codes...

 

I just checked it and it only threw one its P0171, you know my intake tube came off the other day when my wive was driving I think it might be the maf

 

Dude! Make an effort to be understood! How can we help you out if we can barely tell what language you're speaking?

 

Lol, I was thinking the same thing. I am not usually a grammer/spelling ****, but I was amazed he managed to get all that text into only two sentences. Impressive.
