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?
