i am running a GT with a 5sfe. cant pass emissions because of high NOx, and i am running a code 25( air/fuel lean). i checked and cleaned my EGR, checked the resistance on my injectors, put the stock manifold & air box on, cleaned the fuel pump filter, but still have it.
while i was cleaning it i remember one of my friends gave me it as seeing mine was garbage when i got it, he said it came out of a celica, but i think it was an ST. would that make the diffrence? also my motor was blown when the car was bought too, but it had a 3sfe in it. i dont know if the ECU was swapped out too, havent made the effort to look yet. if it is the one for a 3sfe could that also do it too? |

If you have a code 25 you probably want to start by replacing your O2 sensor.....
Is it a 2 stage idle test or is it on a dyno? Can you post up the rest of the results? --------------------  |
