4 cyl 1999 camry p0171 DTC light

Question

Hi..

My 1999 Toyota Camry w/110K miles had a check engine light on when I started it up. Code P0171
The car fired and then died - Check engine light came on. I had to give it a lot of gas to finally catch. - Check engine light remained.
I have no hesitation but I have noticed that the idle when warm is just slightly down but not enough to stall engine.
When I start the car now I give it more gas to catch..Car seems to run fine.
What should be checked/replaced..?
Thanks..

Some of the Camry LE models have a uses a MAF (mass airflow), if this model has a mass air flow check the air duct for any open , or torns, that can cause a false air and set a lean code condition.

 Here is a MAF system on a vehicle with a broke airflow duct , the engine was hard to start but yet accelerated real good, the only code was a P0171 , further inspection was needed

 Here was the cause of the lean code and the hard to start condition.
