when i start the engine and when it goes to almost idle power at around 600rpm i noticed the engine sound's not like before!!! it sounds like a Diesel engine!!!!!
Pls any help to solve this problem!!!!!!
Sounds like the idle is too low at 600rpm, it should be more like 750rpm, if I'm not mistaken. Low RPMs will make your engine sound rough. So it could be your RPMs. Try to take it to the dealer and see if the can adjust it.
