THROTTLE BODY SWAP NO CEL!!!!

[sito]

Hi Guys,

I had swapped my 1NZFE chip into the 1ZZFE throttle body but after one day of driving... CEL light up.. error code 0172 (fuel trim too rich bank 1)

I reset my ecu, and drove again... and the next day... the same error code came out....

These two codes came when i was moving off slowly and with air con on.

I swapped the 1ZZFE chip (part number #22030-0D030) back onto the throttle body and there's no CEL till now. But i could feel rpm oscillations when car was slowing down. By adjusting the idling screw, does it helps to remove the oscillations?

Should i stick to 1ZZFE chip or try making the 1NZFE chip works?

Thanks everyone!

Any advice, please?

Thanks...

Leave the 1NZ chip in. That's the way I have it and it works great.

Thanks for your advice, tk-421.

Are you using the 1ZZFE chip with the 1ZZFE throttle body too?

Thanks....
