Noisy engine idle and stutter at low or high speed

Hi, i have an x-type jaguar estate 2.0 d se 2005, when travelling at a constant speed, high or low, at certain speed ranges the engine is stuttering like a lack of fuel type thing. It does not happen on accelerating just cruising or sometimes decelerating.
2nd problem is when the engine is at idle there is quite a loud rattling noise in the engine bay like something is loose not in the engine but attached to the engine, it completely disappears when the accelerator is pressed, ie the revs are up, only occurs on idling. It does fluctuate high and low but is constantly there.

I had the same problem (X-type 2.0d 2004). The stutter was cured on mine by getting the ECU fashed with the latest firmware. This is a known problem and the update does cure it (£28), I didn't bother with all the tests the garage wanted to.
The noisey engine at idle is the alternator belt. It resonates at idle and causes the noise, There is a modified bottom pulley, tensioner and belt kit, but it is rather expensive ~£200 plus fitting (around 4 hours labour). Mondeo's have the same problem but that kit doesn't fit the Jag.
Hope this helps

My Jag expert, told me it was a missing rubber ring (prob corroded over time) that causes the engine to make a noise against the engine connection to the sub frame. He told me the part cost about 5 GPB but he had to take the engine out, so many hour of labour. He then said that it doesn't cause any harm, just makes a noise, so if you can live with it, don't do it.

Hi it may be an air sensor, air mass sensor.

When you ease off the power they often cut out with this fault. Try cleaning the air mass sensor with carb cleaner, its a easy job. let me know if you are unsure where it is and I will talk you through it.

Hello. I can assist you. Actually the top speed is supposed to be 123 MPH. I would recommend that you have a scan done on your Jag as there is definitely something wrong.

I'm trying to find out how many cooling fan relays are in a 1999 Ford Taurus SE with the 3.0L Vulcan OHV engine. This model year has done away with the CCRM (Constant Control Relay Module), so the relays...


fuse #9 protects the 2 cooling fan relays.

It looks like the hgh speed cooling fan realy is in a thin box mounted sideways between the battery and fender.

It has high speed relay, autolamp relay, autolamp headlamp relay, horn relay, washer motor relay, wiper hi/lo relay, wiper park relay.

Section 03-03: Engine Cooling 1999 Taurus, Sable Workshop Manual
DESCRIPTION AND OPERATION Electrical System NOTE: With A/C ON, the cooling fan motors will run continuously. Cooling fan motors will not cycle ON and OFF with A/C clutch (2884) .

NOTE: An exception to this is when vehicle speed is over 61 km/h (38 mph) and coolant temperature is below 100°C (212°F), and A/C head pressure is below 1.71 MPA (250 psi). The cooling fan motors will then automatically shut off.

The cooling fan motors are mounted within a fan shroud (8146) behind the radiator (8005) .

Engine Cooling Fan Control CCRM Applications The PCM monitors certain parameters (such as engine coolant temperature, vehicle speed, A/C on/off status, A/C pressure, etc) to determine engine cooling fan needs. The PCM controls the fan operation through the Fan Control (FC) output (single speed fan applications) or the Low Fan Control (LFC) and High Fan Control (HFC) outputs as shown in Table 2. Although the fan control (FC), low speed fan control and high speed fan control relays are normally open relays, the FC/LFC circuit is wired through a voltage inverter inside the CCRM. The voltage inverter ensures that the PCM must turn on (ground) the FC/LFC output to turn the fan off. This is done so the cooling fan will operate in the event of an open FC/LFC circuit.

Stand-Alone Fan Control Relay Applications The PCM monitors certain parameters (such as engine coolant temperature, vehicle speed, A/C on/off status, A/C pressure, etc) to determine engine cooling fan needs. The PCM determines engine cooling fan control requirements and controls the fan operation through the Low Fan Control (LFC) and High Fan Control (HFC) outputs (Table 3).

I have a 55 plate 2.5 S Type. I bought it from a local Jag dealer, i had a few small problems but they sorted them out straight away.
