Symptoms of blockage are a decent idle when cold, which gets worse as the engine warms and then leads to complete stalling at working temps.
Why does my Zetec engine stall at 700 rpm?
Symptoms of blockage are a decent idle when cold, which gets worse as the engine warms and then leads to complete stalling at working temps. The engine seems to pulse and hunt with a one second frequency between 1500 and 700 rpm The arrow points to the rubber tube running to it. To change it, remove the rubber T piece under the coil.
Can a Aftermarket cold air intake really work?
Aftermarket Cold Air Intakes Are Only As Good as Their Engineering. While it’s true that aftermarket air intake kits can improve performance by a) removing restrictions and b) reducing air intake temps, the truth is that these improvements are meant to be part of a system.
Are there any issues with the Zetec engine?
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.
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.
Why does my focus engine shake at idle?
About 2 weeks ago my idle has gone to crap, the rpms will dip very very low when at idle and my engine literally shakes because of it and will stale at times. If i apply a bit of throttle it will smooth out and run ok..

Why is my Zetec engine stalling and stalling?
Hiding underneath your coil is the most vulnerable part of the Zetec and few seem to know its there. 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.
How can I test my Zetec pulse air injection system?
To test, go under the front of the car and remove the vacuum line from the pulse air injection system black box. Connect a vacuum gauge. You should get vacuum only on a cold engine and overrun. If there is any vacuum at idle on a hot engine then the solenoid is broken.
Why does the dpfe sensor on my focus fail?
This excessive amount of EGR combined with the air coming in via the throttle body leans out the fuel mixture, causing a lean misfire, which is the “stumble” or “hesitation” that is common as the DPFE Sensor fails. The DPFE sensor in the Focus is not very robust, requiring frequent (every 30k miles or sometimes less) replacement or a work around.
Where to talk about a 2002 Focus SVT?

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.
What should idle speed be on Zetec gomog?
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. Idle Speed Control valve There is an idle speed control valve. This allows small variations in idle speed to be smoothed out.
How do you do an idle Relearn on a Ford?
