Hi all,  
Having RPM issues with my cars. Sometimes it works just fine (usually after sitting overnight). When I drive in the morning for the first few minutes works fine then RPM won’t rev more than 2000 rpm.  
When I turn the car off and wait a few minutes sometimes it will work.  
Replaced MAF Sensor and throttle body.  
Still having issues… Any idea what can be causing this?  
Mechanic has no idea…

I bought the car in Korea… It’s the Korean LF Version…  
So no warranty…
