Quite possible you have a bad ignition coil. As coil heats up it breaks down and will not return to normal till it cools down. Check for spark the next time this happens. If spark is weak or not there, it warrants testing or replacement.

PO700 is a code telling you there are codes in the TCM of some late
model cars where the Transmission control module has been removed from
the PCM the vehicles main computer , And basically it happens when the
TCM has a issue within itself or the transmission that sets a code and
it sends a request for the PCM to illuminate the SES or CHECK engine
light. To get at the TCM codes requires in most cases the most up to
date scanner software purchased after the cars model year and as of yet
is still a little iffy. Standard OBD11 scanners will generally not be
able to see these codes.
P0335 (Crankshaft Position Sensor A Circuit Malfunction) first disconnect the CKP itself and inspect the connector and terminals
for corrosion. It should be clean and dry. Make sure the weather-tite
seal on the connector is in place, uncontaminated and undamaged.
Resistance of the CKP should be 500-900 ohms.
If all good, trace the CKP harness upwards as far as you can (until it
enters the main harness) and make sure you don't have any "rub-through"
or spots where the wiring appears damaged.
DTC P0421 Warm Up Catalyst Efficiency Below Threshold (Bank 1)
DTC P0431 Warm Up Catalyst Efficiency Below Threshold (Bank 2)
Its too coincidental for both
catcons to fault so there's something in common to this error (I feel
is) upstream. First there's a V6 engine with separate sets of cylinder
banks serving separate catcons with separate pairs of O2 sensors. For
both rear sensors to come up simultaneously indicating low efficiency
and "runs fine but strong exhaust smell, maybe running rich(?)"
suggests a component in common to both cylinder banks; maf, map, iat,
ects, tpp, etc.. Any one of these parts plays a role in the overall
effect of a running engine and most likely needs monitoring while the
engine's running with either Saturn's Tech-tool II or better
readers/scanners capable of displaying live data to discern subtle
faults translating to either a constantly rich or leaned out condition,
abnormal running. Without other error codes to go by, there may be no
choice than to seek Saturn diagnostic services other than a local
expert capable of interpreting all the information from live data
displayed onto a graphics screen to read from all the sensors.

P2119- THROTTLE CLOSED POSITION PERFORMANCE
Possible causes of DTC P2119: Weak throttle body return springs
Throttle plate sticking due to carbon build-up.
P0102 code relates to the Mass Air Flow (MAF) Sensor. The mass airflow
sensor measures the speed and density of the air entering the intake
manifold. The engine computer converts this input to a Mass of air per
unit time to correctly fuel the engine. the code P0102 will set if the
MAF sensor signal voltage is less then 0.20volts.
Code P0507 will set if the actual idle speed is greater then 200RPM
from what the engine computer has commanded. Possible causes for this
code:
P0507 is high idle when the PCM wants lower. If you have the 1.9 LT
SOHC engine in the 2000-2002 year range this is normal caused by a
leaking intake gasket. Can be other sources of vacuum leak or something
else that keeps the RPM up when it should not. It may be the Idle Air
Control valve sticking.
The other two codes P037 and P044 i an not sure and the code P057 was a guess of P0507 since it's seams to be in the area where the problem is . The P0404 i am guessing it's going to be EVAP problem like a lose or bad gas cap. P0370 is (ECM) replicates the signal received from the
crankshaft position (CKP) sensor. This signal is sent to the fuel
injection control module (FICM) through the engine speed signal
circuit. The FICM uses this replicated signal to generate injection
current and control the recharge of the fuel injection high voltage
circuits. When cranking, the FICM has full control of the fuel
injectors. The only input the FICM uses at this time is the engine
speed signal from the ECM. The FICM monitors the signal along with the
injection request signals from the ECM after the engine is running. If
there is a problem with this signal, a DTC could set.
Start with the simple and clean the Idle Air Control (IAC) valve, and the Mass Air Flow (MAF) sensor. This may help the P0421, P0431. and then check the crank shaft sensor wire harness and replace the sensor, which should take care of the P0370. *** for the P0404, check the gas cap if not replace it. Good luck and keep me posted.
SOURCE: i am getting the codes
The codes are as follows,
P0320 does state it is for the crank sensor. If this codes comes back even thought you replaced it, there is still an issue, maybe wiring, but not common.
P1299 states a vacuum leak, and that the idle air control valve has closed, maybe due to the vacuum leak. These are two seperate issues, but may be related.
I'm assuming you cleared the codes and they come back?
Look around for an air leak, as it may be an intake leak. Sometimes you can spray carb cleaner around the gasket area to hear if the idle changes, to try to find the area.
Also, call a dealer to see if there was an issue. Some times dealers had to "flash" PCm's due to bad software.

no i guess itz not the graphics card..itz probably causing from faulty or defective ram or main/mother board..
however, proceed to verify with the below stated steps, only if u r a professional..
DO IT ONLY IF U R A PROFESSIONAL..
..plz do check the following as in order:..
the Hardware part:..
1) check mains/power supply..the fuse, switch, wiring n associated circuitry..
2) [in case of desktop] the
smps itself may b defective/faulty..check the outputs of smps viz. 0v
(black~ground); +12v(yellow); +5v (red, green~ps-on, violet~pg&
grey~sb); -12v (blue);-5v(white); +3.3v(orange)..
check the battery n adapter [main power], in case of laptops..
replace with a standby n see..
3) unplug mains supply..pick open/remove the cmos battery..check (above +3v)..resit..
4) open the cpu n see if heat is generated..if not..replace the cpu n see..
5) open the CPU Heat-Sink with fan out of the
socket..put some "Heat Sink Compound" (available in local electronics
chip level spare market)between the cpu/processor and the CPU Heat Sink
*** fan..resit/fit it tightly in position..
6) on main/mother
board..see with a debug card for mb error..may b short..look for
defective capacitors(espabove1000mfd)/mosfets..go through the mb's
south bridge n the circuit lie around atx connector..the crystal clock
generator (if cpu isn't heating up)..
replace with a standby n see..
7)see
if the ram(s) is loose/faulty..open clean/remove carbon & or oxide
formed on the teeth with an eraser n resit it..or replace with a standby
n see..
8)remove/clean dust
neatly..dust is non-uniform in nature n may cause
jam/short circuitry/excess resistance n many more..resulting an increase
in heat..
plz give priority to steps(2, 5 & 6)..
if u r not a professional, always better to seek advise from ur system admin/vendor....
