**edit by moderator** i notice my engine was knocking horribly. the battery also drains down when it idles extremlley rough, it is mis firing alot n i think it may be runnin on only 4 cylinders as of now. My cat is gettting extremley hot which means its misfiring n i have no idea what causes this n why the voltage drop. thanks

Is the accessory drive belt attached? Does the crankshaft pulley wobble as it spins? Is the coolant level to the top of the radiator, and is the recovery tank full? Can you tell if the noise is coming from outside or inside the engine? From the front or back? High or low? What is the engine oil level? What is the engine oil pressure when warmed up? How long since new plugs and wires? Are the battery cable connections clean and tight on all attachment points? Have you tested the battery or alternator? Is the engine bouncing around or rocking a lot as it misfires?

Your answers will help lead us to a diagnosis.

And where are you located?

coolant level should be good just had a recent flush about 3 thousand miles ago, battery is good, new performance wires n iridium plugs about 6 thou ago n i am located around PL minnesota

SHOULD be good? Go out and check it now please. There'* a very good reason this needs to be ruled out.
