hello ,

form week till now i have problem in it , when i drive my car for along time and along way ( 50km and more ) then try to stop on light ( on D of course ) , the RPM go down (400) and up to normal , when RPM go down the engine start shakes like the car it will turn off , and some time its turn off while A/C ON .
This problem just happen with me when drive on long way but in the city i have no problem ( in morning on short way i have no problem )
