What should the idle speed be on a Zetec?
What should the idle speed be on a Zetec?
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. Idle Speed Control valve There is an idle speed control valve.
What kind of starter motor do I need for Zetec?
Starter motors are pretty straightforward as one from a Ford CVH engine (Lucas part number LRS707) will bolt straight on. You can also use one from a Pinto engine, although it will need a 14mm spacer between it and the engine to give the correct pinion throw.
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 causes Ford Focus 1.6 Zetec to cut out?
This feature is not available right now. Please try again later. A common problem with the Ford Focus 1.6 Zetec is that the engine starts to idle too slow and can sometime cut out. This is often caused by dirt clogging up the throttle body and restricting the airflow to the engine. Here is a brief how-to video to fix it. Loading…

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.
What kind of engine does a Ford Zetec have?
On top of this, there’s a smaller capacity Zetec – described elsewhere – plus, late Zetecs were made to look like the latest Duratecs. Early, ‘Silver Top’ engines (with an aluminium cam cover) were fitted to Escorts from 1991 onwards, late Fiesta Mk3s and then the Mondeo.
Why is the Ford Zetec on the back of my car?
The unit evolved into the Black Top unit The name Zetec is pretty confusing because it’s now used by Ford as a badge on the back to describe a level of trim. On top of this, there’s a smaller capacity Zetec – described elsewhere – plus, late Zetecs were made to look like the latest Duratecs.
What should I tune my Ford Zetec E to?
Both the ST and RS engines were confusingly re-badged as a Duratec. As far as tuning goes, it’s simple to bring an 1800 up to RS1800 spec with Ford cams or Kent FZ1802 cams – you would need a 130bhp ECU though, or aftermarket re-mapping. A power boost valve will help eliminate the flat spot between 3,300-3,500rpm.
What should I know about the Ford Zetec engine?
Competition cams are designed for maximum power at the top end of the RPM range, a place that most daily commutes will not permit! Some Zetec engines respond better to less aggressive camshaft durations check your engine on a rolling road. The map and fuelling also have a large bearing on the torque gains you’ll make.
What kind of engine does a Zetec Rocam have?
Zetec Rocam (Duratec 8v) In 2000, Ford of Brazil developed a cheaper version of the Zetec-S engine with single cam and 8 valves driven by a chain. As a result, this engine exhibits rougher behaviour, producing more vibration and noise.
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.
When to change the idle on a Ford Zetec?
Ford says that it should be changed at 30,000 mile intervals but then they forget to mention that in their service guides and Haynes forgets it entirely. I am told it is very difficult to change. 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.

What causes a bad idle on a Ford Zetec?
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.
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.
