Heavy black smoke from exhaust during the acceleration
Smoke in the exhaust is a result of either too much gas or something other than gas being burned and there are a couple possibilities of what else could be burning. So there's a chance that either you mixed something in your gas you put in, or your engine is burning oil, you are burning antifreeze, or you're just burning too much gas but the engine wouldn't run very well. You didn't say anything about other issues...like how overall the engine is running but the engine could just need a tune up?
But antifreeze usually burns white so because you said it was black smoke (usually more blue colored when oil is the cause) I don't think it's antifreeze.
Black smoke can appear due to an engine that needs a tune up but it's usually not that noticeable.
The most common reason for heavy smoke coming out the tailpipe is because you're burning oil.
If you find you have to add a lot of oil regularly to the crank case and there are no obvious leaks (look for spills on the pavement where the bike is parked) then you're probably burning that oil and with the smoke you see...that just about nails the cause of the smoke.
How do you fix it? Usually you have to change the rings on the cylinder/s. Cold be one Cylinder or all of them. But generally if you do one cylinder you do them all since while you're doing it...why not do them all?
So based on what you've said...that's the best I can do.

Why is there air in my coolant system after i bleed system to gm stanrds
The 3.4L is known for blown head gaskets. I personally have repaired over 30. One of the first signs is air in the cooling system and loss of heat. The best way to tell is to chemical test the cooling system to see if there are CO2 gasses entering the cooling system. I've seen people bleed the system and it is fine for a while, but believ me this is a blown head gasket.

How long should a cv shaft last?
Depending on how hard it's driven, it should last a min. 50,000 mi. and up over 100,000. Check the rubber boot and see if it's torn, if it is then dirt is getting into it then it won't last very long..5 to maybe 10,000 mi.

Have installed air raid cold air intake system on 2006 Colorado in spring first cold night off fall having new system exp eng fault code dtc po 128 could intake temp be causing issue
Sorry, but this is an engine coolant system air temperature problem which could be a mixture of the abundance of incoming air mixed with engine coolant actual temperature and its freaking the PCM out. Which you do not want during the winter months. If you have the other air box to just reinstall it, if just for the season. You want to know your vehicle is 100% during the cold weather to prevent long cold walks. Plus yyour getting plenty of cold air during winter anyway.So just but everything back for now to just change it back over during the spring this is a simple problem glad to help.Thanks in advance please remember to rate and leave testimonial this is

Car starts then dies out
Crankshaft Position Sensor, bad coil packs, clogged fuel filter/fuel pump completely broken, among a plethora of other things like the on-board computer itself.

Slow to shift into 2nd gear slight vibration low speed
Sounds like they may have drained your transmission fluid instead! Look in the Owner's Manual on how to check the transmisison fluid and the engine oil - do not drive the car 'til you check these!
The tire sensor will need to be replaced - either check on Ebay or call the dealer for the part, or a tire dealer may be able to fix it.
