WHY DOES MY IDLE EXTREMELY ROUGH AND GETS WORSE WHEN THROTTLE IS PRESSED?

1990 Toyota Camry

It starts up and runs but vibrates extremely hard when idle and harder when throttle is pressed. Plus oil splatted all over passenger side under hood.

Check front main seal on crankshaft for oil leaks. As far as the start up, check fuel pump pressure, check for vacuum leaks, and check for issues with the iac.
