When your 1994 Jeep Grand Cherokee is running with or without the air conditioner on there is a rattling noise you can hear outside really well Does this mean your air conditioner is going out?

I own 2 Jeep Grand Cherokees. I had the same issue with one of mine and it turned out to be a bad catalytic converter which was making that nasty banging noise. It would mostly make the noise when sitting in one spot idling the engine. You will have to get that replaced before you can pass any future emissions tests. Good Luck It might also be your water pump going out. Where does the sound come from? Front of engine or below? If it is front - check water pump. Remove fan belt and see if water pump will wiggle up and down. If below, does the engine emit a 'stinky; smell. Sometime, the c-converter can emit a methane like odor.

Why is 04 Chevy Tahoe making rattling noise when you press on the gas?

Try to locate the rattling noise. I would especially check the catalytic converters if the noise sounds like it is coming from underneath the vehicle. Usually throughout some time the honeycomb material inside them will break up from 'heat stress' and will rattle around there. In some cases it can get lodged int he pipe between the converter and the muffler blocking some of the path of the exhaust causing some major performance issues.
