Mazda 1.6 Engine Issue

Hello everyone ! Here is my name, Fabien

My friend bought a Mazda of year 2001 with 58 000 km, it's the 1.6 DOHC engine with 98 HP ( 72 KW ). We live in France

We got a problem to make the car running great.

For now, the car start and idle correctly cold and hot... The problem is when we want to throttle...

The car got VERY VERY low power... it bog a lot... I got some video to show you what's wrong with this car :

When we go for a ride it's a lot WORST... It's not running good at all..

Sometimes the check engine light come and we got : P0171 too lean code... But 90% of the time, no check engine light. BUT even if there is not check engine, the car ALWAYS run like this... Really bad.

Spark plugs are reaaaallyyyyy white...

For now we changed :

Timing belt
Camshaft sensor
Crankshaft sensor
Fuel pump
Spark plugs
Air filter

And we checked the intake tube if there is no crack.. of course no crack

We cleaned fuel injectors..

What can we do to make the car run better ?

We made engine compression test, we got 12 bars on every cylinder so ~175 PSI...

I know this engine is almost the same as mazda protege.. So this is why we try something here ! We know how to use wrench so if you have something please tell us.

Thank's !
