moring start is the worst thing to me, the car starts propperly but it keeps shaking till the RPM reaches 1400, at the bigening it stays at 900 RPM. but after a while it works properly.

the second thing is while breaking the RPM drop down to 500, then it comes up to the normal average, does these problem cause knocking with the engine.

i changed coolant, knock and crankshaft sensors, to get rid of the issue but I'm still no use.

also i have gas smell after any kind of drive
