the engine will stop if i step on the gas to fast, and its no power left when i accelerate. i have to go very easy on the gas or else i feel it would drown. i had a diagnose test and then code 44 flash in the engine light [oxygen sens.lean]. not long ago a guy took a test and he said the temp sensor was the problem, but that code did not occur this time. is it the same if i take the test with cold or warm engine? whats the best thing to do and where should i start? buy some new sensors?

Could be caused by one of the following below

Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
Fuel contamination.
Foul/defective spark plugs.

Note:If it doesn't apply disregard it and keep testing.
