P015b trouble code any ideas

Hey guys my car was broke into yesterday night and I had to replace the ignition lock. I have the lock in, but I have no Idea how to disconnect the old anti theft wires to install the new ones. I have a 92 lesabre. Thanks

I have a 92 Buick lesabre. The engine smokes pretty bad. I thought it was the valve cover gasket, but after replacing it today it still smokes. What are other reasons for white smoke under the hood? Could this be intake gaskets?

I just bought this car yesterday, I was able to get the right side to flash yesterday after replacing a bulb, but then a couple hours later it stopped flashing again. I have replaced the flasher for this car and it still wont flash on either side. All the bulbs illuminate so I'm pretty certain...
