Ok ill list everything i have noticed.
The car idles at 600rpm and it sounds sometimes like it is going to stall, because the car starts to vibrate.
When I open the hood, and listen to the engine, about every 3 seconds it sounds just like the engine is taking a gasp of air.
And also I have noticed a crack in my radiator where the green coolant leaks out.
Can you guys link any of this together and maybe figure out what might be going on? Thanks for responding.
