make a long story short:

Check engine light on...autozone said its bank1 sensor bad and more then likely it was the 1st o2 sensor near the engine. I bought a bosch o2 sensor and put it in...car bogs like crazy when I gas it. I put the factory o2 sensor back in, now does the same thing......just confused right now....Before anything was done...My car stalls a bit through out the each gear on low rpm. But after 3500+ rpm its runs fine, only when I shift and drops back to 2500+ rpm it stalls on me...so thats why I changed the o2 sensor.....

reset the ecu and triple check all the wires and its correct.....need help bad.....confused now.....factory and bosch sensors are bogging out on me when I gas it.....??????

 

dont listen to people at autozone.. what code you throw? did you get the right sensor? install it correctly?

 

P0171 (Too Lean in Bank 1, Sensor 1) came up on the scanner....

 

someone help me asap.....this is a my daily driven car.....im just so clueless right now.....at idle...its normal...when I gas it, it chokes and rpm drops to about 500 rpm and then 3-4 seconds later it will slowly climp up(stalls).....each time I shift it stalls real bad........im like going no where....

 

Sounds like you have a fuel issue not an O2 sensor issue.

 

I had the same problem while back!!!!. It was my fuel filter! might wanna check that.

 

anymore input?

 

02 sensor would not mess up wide open throttle fuel maps. it would just expletive with the partial throttle maps

sounds like too rich or too lean, so check the fuel pressure, fuel pump, fuel filter, fuel pressure regulator and injectors/fuel rail. if they are fine, move onto the ignition. fuel+spark = boom....so its either one
