Since i raced my car last.. i fouled out the plugs and sucked the screen from the maf into the intake... it didnt get past the sensor so i just replaced it. Of course my plugs were fouled but now the car runs ok it idles at 14.9 starting but as soon as it starts to warm it jumps down to 10.0... even cruising it only leans out to 11.6 or something... just dumping fuel. It does have a code for a bank 1 sensor malfunction.. but i dont see how it would make it run that freaking rich... If anybody has run into this let me know

and i cant afford a freakin $dollar sensor from mitsu.. anybody have a part# for a universal one that will work>?

 

nobody??

 

have you reset the ecu? It sounds like it's in a limp mode the throwing fuel.

 

if your first o2 sensor is bad it will run rich

 

yeah.. i ahev one from autozone that is universal but i dunno if it will work....

No.. the ecu has been reset and it throws the code right after the car is started,....

my friends 35r did the same thing when we built it last night... replaced the same sensor and it still throws the code.. but we were welding under the car while he was flashing with the ignition on so im thinking it shorter the sensor on his.
