My 96 Sport has recently developed a fairly loud ticking noise (coming from underneath the vehicle. At first I thought it was the valves tapping but after checking it out it sounds like it is coming from the transmission or somewhere in that area. Does anyone have any ideas to what this could be? One person told me that it might be the heat shield on the cat converter and another said that it is probably the fuel injectors. I'm not buying the fuel injector theory and it doesn't appear to be the heat shield.
