Question about Cars & Trucks
The back firing makes me think that when you put the new dist. in you got it one-half a tooth off. I would bring #1 cyl. to the top and remove the dist. cap and be sure the rotor is pointing to #1 in the firing order.

Have u checked for vacuum leaks or poss leaking EGR valve? use carb spray around the upper intake manifold where it bolts to the lower manifold, spray vacuum lines where they are connected to the engine vacuum ports, the idle speed will change if u hit a leak, as far as the EGR valve goes see if it gets hot at idle, if it does it is leaking, if all checks ok replace the O2 sensor, but i suspect u will find a leak at the upper intake plenum.

Check your fuel pressure, and or injectors. You may have too much fuel getting into the engine causing it to burn rich and overheat the converters.

Check your coil output, buy a cheep spark tester. Pull of a spark plug wire and plug in the tester(ground the other end), set it to bridge a gap for 30,000 volts.Have someone start it and make sure the spark will jump the gap on the tester.Danger-Very high voltage! It will light you up if your touching the tester while the car is running!You'll be able to see a bright blue spark(and hear it as well) if your coil is good.If it's a yellow thin spark it's probably the coil.
If you have good spark, check the fuel filter and fuel pressure at the fuel rail.
Back firing could be timing,cam position or crank position sensor.Worst case scenario, timing chain or belt.

a lot of people have reported this issue with the 2001 Nissan altima. it is a design flaw and the idle rpm fluctuation is caused by a bad intake manifold gasket. the part only costs about 10 dollars but do to the 5-10 hours it takes to replace it is a very costly on the labor side
