After the engine warms up and I drive for a few minutes, sometimes my engine will stall when I brake. At startup the idle speed is fine and when it's warmed up it seems fine too, but when I have to slow down, the RPMs will dip really low and sometimes the car will stall. Would someone please tell me what the problem could be?
Problem 2 is when I'm driving my car makes a noise. I don't think it's the engine because when I'm idling and I rev the engine, there is no noise. I thought it might be the tires and I changed them (because I was desperately needing new tires anyway) and the noise is still there. If you know what the problem maybe, please let me know.
