Question about 1996 Pontiac Firebird
Just bought 96 Firebird from the auction drove it home. When I arrived vehicle begin smoking from the cataylic converter and the motor however no smoke comes out the tailpipe and there are no leaks what soever what's the problem?
Cat converter probably over heating or is blocked and that is blocking up the exhaust pipe. Consider replacing it.

SOURCE: Blue smoke comes from tailpipe
A lower octane gas woudn't cause it to blow blue smoke, more like it needs an engine job. There is oil getting into the combustion chamber, could be valve guides, valve seats, piston rings worn.

Sounds like the motor is going bad. Does it have an electrical smell to it?? Usually when the motor goes bad it will smoke. The only reason it will only work on 4 when it is smoking is because that is the only setting that applys enough amps to actually spin the motor. A shop would be the best place to take it as these motors can be somewhat of a pain to replace.

I would almost bet you have a blown head gasket or a cracked head. White smoke at the exhaust, loosing coolant, moisture on the underside of the oil fill cap, and on the dip stick are all signs of a blown gasket. The fact that there is no coolant in the oil does not mean it does not have a blown gasket. To find out for sure remove all spark plugs, disconnect the coil wire, and then run a compression test on all cylinders. If you find one or more with low compression you have a blown gasket. Do not drive this car any longer until you get this repaired. Serious engine damage will occur if you continue to drive it.
