Hey Guys... I've had mid 90's GM B-Bodies my entire driving career, so excuse my newbness if you will. I have 2 problems that I need assistance with


1. My passenger floor is flooded with disgusting, dirty water. If i'm not mistaken, that is indicative of a heater core problem.. right?

2. My car does weird things while accelerating. From a stop, it makes this large boom after stuttering for .5 seconds. It sounds like its a drivetrain issue. Also, anything above 40mph and she shakes like a recovering addict. It feels like more than just an alignment issue.

ALL INSIGHT IS WELL APPRECIATED!!!
