Blue smoke means that you are getting oil into your cylinders. The car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.
Did you replace it with a OEM or aftermarket CPS? If you replaced it with a aftermarket one then you are most likely going to keep throwing this code. Or you have a bad sensor
Check the leveler first. But from your description it sounds as if the compressor is shot itself.
This is very easy to do yourself. It literally plugs right into your air intake and has two wires running to it. Right off the top.
Check your fuses, if they are good, then check to see if the switch is functioning, if that is good, then it is either off track or the motor is bad.
AC Control Module. You can find it at your local auto parts store. Easy to install yourself if you pay attention to what you are doing.
I own the same year make and model. I would not give it up for anything. We both out weigh most of the vehicles out there. They are not that top heavy, and because of the weight of the Suburban they keep traction really well. Very safe vehicle to be in. From the Fire Department "The vehicle with the most lug nut almost always win."
You could also have tires that are out of alignment.
On these vehicles it is usually Bank 1 before the catalytic Convertor. But one common problem that I have seen is that it VW will throw the P0420 code, and the Catalytic converter is bad. I would first though start with the bank 1 then go from there.
There is a few answers to this question. First I would get the tires checked again to make sure that they are balanced properly. I have seen many times when they are not aligned properly and they cause a shake. Second, the mechanic would not have checked the bearing when replacing the brakes due to the fact that he did not have to take off the wheel bearing to get your rotor off. Third, After getting your tires checked for proper balancing, make sure you also have an alignment done. I would take it to another shop to have them inspect the car.
