For a while now my 89 sc has occasionally had hard starts and engine drops and just yesterday I came to a red light and noticed the tach jumping from 2500 rpms to 500 rpms. It wasn't just the gauge the engine was actually sputtering along with it. As I got above 2000 rpm the car seemed normal with some engine blips. Anyways I figure it could be the cam sensor or fuel pump (my pump is whining and is on its last legs). I replaced my crank sensor and dis a couple of months ago so It wouldn't be that. What do you guys think??? THanks.
