Start car and check the PCV hose that connects to intake manifold to pipe under coil. They will collapse and leak causing a rough idle. Also the passenger side motor mount is a fluid filled mount and after time it will transfer engine viberation to the body.

The most common cause of a 1996 Ford Escort to idle rough is bad spark plugs or bad spark plug wires. A plugged air filter will also cause it to idle rough.
the radiotor or the cams
vaccum leak
A bad IAC (Idle air control valve) or a vacuum leak or both.

my local ford dealer just quoted me £13.22 plus vat,so about £16.00 to fit an x reg 2000 1.8 petrol.mine is well split and causing a rough idle...
P1000 on any ford means you have cleared the PCM codes and it hasn't run it's self-diagnostic tests yet. This will go away. It is not related to your rough idle.
injectors are a common problem
