Why do I have a vacuum leak on my Zetec?
If the idle changes, you have found your vacuum leak. There are many vacuum lines around the Zetec engine. The plenum chambers can also chafe vacuum lines. Alternatively, you can also use a vacuum gauge and test. You should have a nice steady 17-20 psi vacuum at idle. Cure the leaks, cure your idle. Look here under plenum leaks.
What kind of spare does a Ford Zetec need?
It is a 5cm rubber T-piece that connects the engine block to the EGR valve and the Pulse air system. Due to the movement of these pieces it often splits and lets out vacuum, resulting in a bad idle and or stalling. Many Agents know about this item and it is one of Ford’s best selling spares for the Zetec. At £6, it is cheap.

The Zetec is a pretty reliable engine and can last well in excess of 150,000 miles. But if there is one thing that crops up time and time again it is a poor idle. It can be so bad it can stall the car or cause the revs to hang at a bad moment for that.

Why does the Morgan Zetec have a rough idle?
Bear in mind that all 16 valve engines tend to have a rougher idle than their 8 valve brethren. Also the ECU on the Morgan Zetec prioritizes low emissions over good performance so even on a perfect car, there will be some unevenness of idle as the ECU searches for the very lowest emissions.
