My car is a 2003 Mazda 6(V6 manual trans). Last weekend, I couldn't start my car (dead battery). So I popped my clutch in gear while the car was rolling to get it to start. The next morning, I went to start my car (it started, but it was hard), and drove to autozone to get a battery.
On the way, my CEL came on flashing, the car was stalling at lights, and a very prevalent tick developed, thats frequency increases with RPM. When I got to autozone (less than a mile away), I changed the battery, checked the oil (was about 1/2 a quart low, so I added it). It was still stalling and ticking, but no check engine light anymore. So I added some Chevron fuel sys.cleaner.
Got it back, disconnected my battery for 24 hours, and started it again. The stalling issue was gone, but the ticking still remains. I haven't started the car in a few days since its at home. A week before this I also had 2 CEL's, one for a misfire and one for a bad cat or downstream O2 sensor. Any thoughts?

Ok, So I started it up tonight after a week of being at school. The tick has turned into a rattle, and my O2 sensor's voltage (Bank 1 Sensor 2) is high. The car idles at a constant rpm like normal, but the engine just sounds "rough", like a tractor. Its shaking/vibrating more than normal. I got below the car with it running and I hear the rattle coming distinctly from the front cat. Loads of smoke coming out my tailpipes. Sound like a bad cat then? Thats what I'm settling on.

Bad fuel injector, but usually a ticking from the fuel injectors signify they're working. Bad spark plug possibly. Damaged wire, coil pack or distributor cap, not sure which one your car uses. Timing might be off. Go have a tune up done on it, or do a tune up yourself.

Check all your plug wires to make sure they all on tight! Cheap trick for this is start your car at night with no flashlight, if any are loose you will see blue sparks. Next, the catylytic converter may have plugged or even started closing up. If they go out completely they can choke the engine to the point that it will not be able to run. A muffler tech can check the cat.

Its` impossible ti diagnose a noise without hearing it; but since you mention the missfire; the ticking could be from a spark not making it through to the sp. plug. With todays high energy ignitions (80,000 v +) a spark can sound like a bad lifter! As for the other issues, its hard to say, but check this first and see what happens. Then come back here if your problem persits.
