Hello,

At the beginning, I apologize for my spelling, but I write from Poland and my English is at a communicative level.

I have a problem with my G37x 2013.
After the engine warms up, the revolutions around 900-1200 are falling to 500. This is only after adding the gas to this range. The above is ok. The suction is ok. Only how the car will reach the working temperature.
When driving in the city it is annoying.
SES is not light. There were errors P0011 and P0300, but they are no longer in error.

I changed the oil, I used a rinse aid before replacing it. I replaced the air filters. I also cleaned the MAF.

I also did adaptation of the throttle and free spins, but I know if it was successful.

I now plan to clean the throttle and re-adapt.

Has anyone had a similar problem?

thanks, Paweł

 

Cleaning the throttle bodies will probably fix your problem.

 

unfortunately it did not help

 

Did you perform the idle re-learn procedure after cleaning rhe throttle bodies?
