Some troubles, should I start worrying or no?
Well, before I issue the problems that I think I am having with this car, I will tell you guys my past modifications. This will help you guys and me. Also, I am a newb at all this, so yeah.
I have a 1995 Honda Accord DX.
The first thing I installed is a ebay muffler. 2.5" inlet and 3" outlet. The guy from the muffler shop installed a 3" custom catback with mendrel bent piping.
The second thing I installed was a custom cold air intake, and it uses a plastic vent piping.
I then took out the O2 MAP Sensor from my intake manifold and replaced the hole with a bolt. I just leave the O2 MAP Sensor hanging out in the engine. Supposably it was to trick the ECU into thinking that colder air is coming in.
I just baught new headers 4-2-1 (2 pc) headers and salvaged NGK spark plugs wires from a 1993 Honda Accord (non-vtec). Then I baught Bosch Platinum +4 Spark Plugs. I installed them all, and this is where I realize the problem...
My car rattles! It sounds like a muscle car. The car sometimes idles below 1,000 RPM to a point like it is about to die. Their is a crack in my catback now. Their is also an oil leak from the oil pan. Also, I am running too rich. Too many black resin from the rear.
Can somebody help me out? Thanks, I'd appreciate.

Whoa....first off, why did you get used spark plug wires and brand new plugs? You should use new wires when you change your plugs. NGK plugs are best, since you have an import.
The sensor...you just put a resistor in it right? One of those "it'll give you 20hp" things? Take the resistor out and plug the harness back in....
The headers aren't really a problem but the crack in your catback is. Your car is running rich because of the sensor being unplugged and that's why you're getting a lot of carbon out of your exhaust.
Get the oil leak fixed, and get your exhaust welded up. The reason your car rattles and sounds very deep is because of your exhaust leak. It will give you bad performance as well.

BTW, I had good results with Bosch Pt+4 plugs in my GSR. But most everyone else around here has had problems.

O2 is oxygen, and the O2 sensor isn't located anywhere close to the intake manifold. MAP stands for manifold absolute pressure. Why would you think that would fool the ECU about TEMPERATURE?
If you feel the need to muck around with the sensors, you should first learn what each one of them actually does.
