Question about Saturn L300
I try to start the car but not start or only with difficulty and when you turn on only at 3000 rpm and throttle all the way, and if I lost a little rpm turns off after 1 Low Minute to 1500 with the accelerator Basically, after 30 seconds off, change the coil pad and spare plug, clean the canal that runs from the intake to the EGR valve revice voltages computer and coils.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

sounds like an air flow problem and your fault code points to lean mixture when you take the fuel filler cap off is there a hiss ? if yes change your fuel filter, if no try the air flow sensor

there is a problem with the timing chain tensioner on these models, which causes poor driveability, normally the engine management lamp would be illuminated too

Tips for a great answer:
Inspect the EIS towers and plug the wire connections for corrosion or other signs of poor retention at connections.
The electronic ignition (EI) module supplies a signal to the PCM whenever it determines that the #4 cylinder fired on its compression stroke. Because of opposite coil tower polarity, the simultaneous fir of #1 and #4 cylinders are of opposite polarity as well. Under most conditions, except decel, the waste spark cylinder fires before the compression cylinder in sequence. The EI module can determine this polarity sequence and voltage amplitude by using capacitive pickup plates located under the 1/4 coil. If the module senses a positive to negative sequence and high negative spike when #4 is on TDC, it pulls the PCM cam signal to ground signaling that #4 has just fired on compression. This signal along with the double pulse received from the CKP sensor, synchronizes spark and fuel timing.
Beside plugs , plug wires need to be replaced as well !
