Here are my two DTC's:
2 DTCs Found:
16487 - MAF Sensor (G70): Signal too High
35-10 - - - Intermittent
16505 - Throttle Position Sensor (G69): Implausible Signal
35-10 - - - Intermittent

-Also when comming to a stop my rpm's start jumping and car stalls out near idle. Can someone help me please??

Check to see if it's damp. Also check for a firm connection and see if you need to clean out the connector for corrosion.

That is for 16487.

For 16505, it says the same thing about the throttle position sensor harness (check it and clean it). It sounds like you have an issue with the MAF sensor harness.

Hopefully that's the issue, because Bentley also says to replace the ECU if the harnesses are not the issue for the 16487 DTC.


From Bentley:
The malfunction "P0103 / 16487" is set as soon as the signal voltage rises above 5 volts for longer than 0.5 sec (engine speed below 2000 RPM).


The malfunction "P0121 / 16505" is set at a coolant temperature of over 70C (158F), enging speed between 1500 RPM and 3500 RPM for longer than 2 seconds and an engine load over 66% (Mass Air Flow sensor signal) as soon as the sensor signal voltage is less than 0.96 volts (corresponds to a throttle opening less than 12).

yeah just checked them they are all clean and not damp

I would clear the DTC's and start the car and wiggle the connectors to see if that sets the DTCs.
