I have an 88' automatic that idles really hard when I start her up, shakes and I can hear the tap clicking accessively. Whenever I try to put her into gear either Drive or Reverse theres a flux in the fuel, and my car revs a little then dies.I've started her in Neutral and shifted and while it turns over it wants to die and it has almost no power whatsoever. I press on the gas and it pretty much stays in first gear. Can this be caused by a fuel or oil filter problem? Cam Shaft having valves stuck or is my engine just succumbing to damage from somewhere else?
