Running Lean at Low RPM Load

[Pasteurised]

The car is a Toyota Starlet Glanza V.
I have a wideband and can see that when i pull away from a standstill, if i give the car alot of throttle, it will go full lean and bog down. The only way i can pull away is if i feather the throttle up till around 4000rpm, at which point the car goes fine.

So far ive tried, with no effect, a new TPS, o2 sensor, and FPR.

Cheers

No fault codes.

Car fuels perfectly at higher speed WOT if thats relevant

Car goes lean when i initially put my fut on the throttle, but then goes rich and stays rich right to the end as i apply more brake
