Re: '98 Regal keeps dying, getting codes P0102 and P0171
You have the 3.8L engine right? Is it normal or supercharged version?
P0102 means your MAF sensor is detecting a low input BUT that can also be triggered if you have a vacuum leak.
P0171 means you have a lean mixture. This is normally caused by a vacuum leak, a bad fuel pump or a bad MAF sensor.
Try disconnecting the connector to the MAF sensor and see if it runs fine.
Also you mentioned you have white smoke, this is caused by coolant being burnt, are you loosing any coolant?. This worries me because if one of the head or lower intake manifold gaskets are blown you'll be leaking coolant and have vacuum leaks which if it's not fixed soon can cause bigger/more expensive problems. Another common leaking point is at the pulley tensor, there are a couple of hoses at the back of it which can develop cracks and start leaking fluid. Also below the tensioner there is one elbow running to the intake manifold.
By the way Welcome to the forum!
Best regards,
Oscar.
