I keep getting code P0101 Mass or Volume Air Flow Circuit Range/Performance
I checked the MAF sensor and changed it with a new one. I Reset the code and the car started to run very strong.
The code came back after a day and the car started to runs a bet slow.
and some times the engine dies when coming to a stop.
My car is 2010 S240 with:
1-k&N filter
2-Headers with high flow cats
3-Quick Silver exhaust
4-Tune
Is there any thing I'm missing?? what do I need to look for?
Is it due to the K&N filter ?
Thank you for the help
