Hi all. I am trying to fix a Peugeot 307 1.4 gasoline.
It had LTFT at ~33%.
I replaced the MAP sensor because it was giving wrong readings. Indeed, LTFT+STFT came to ~ 22%.
What troubles me is why it took LTFT about 700 kilometers to come down to 22%.
Has anyone seen this in any car? Should I consider it normal? I mean I have seen LTFTs on Toyotas come down in a few kilometers.
Certainly looking to bring LTFT as close to 0 as possible. Have ordered oxygen sensors. Engine has good compression. Cleaned up the throttle body and the idle circuit.
No intake or exhaust leaks seem to be present. What else could be wrong?
