Get a tune up....the popping noise is caused by excess fuel being burned in the exhaust system,you cant hear it until you take your foot off the gas and the back pressure is reduced...
bad axle joint or ball joints and turn stops can make popping
Yes, it is possible.
When mine did that popping noise it was the fuel pump. But it could be a number of things. It depends on exactly what kind of popping. The Chevrolet Blazer wasn't the best of the bunch. They do really well as trucks. But the maintenance is that of a Toyota.
converter stopped up
Yes, that popping noise you hear is the first sign that they are breaking. It is caused by the disposition of the detectors in the cable or cable port.
Remove the muffler
your starter probably.
If it is too loud, it means the muffler needs replacing. The muffler reduces the sound of the combustion that forces the piston down in the cylinder.
That's where the exhaust pipe and the muffler is, maybe yours is damaged.
Damage. Hole. Perished gasket. Incorrectly fitted. Corrosion.
It means its ove heeted and trying to cool down.
Inspect the steering components, suspension, and brakes.
