Hi there i have a 2006 ford focus and it keeps juddering when in third gear.iv had new leads n coil pack fitted wondering if it may be dirty fuel injectors.can you help!

Is the check engine light on? Read codes if possible. If it runs well and up to redline in 1st and 2nd, I doubt fuel injectors are the issue. Test fuel pressure and for clogged exhaust.

Ford Focus 55 Plate, Engine Light Comes On and Goes

Not uncommon for Ford focus coil packs to play up I've replaced a few I would recommend, replace coil pack and have leads. If you have car serviced at the regular service interval the plugs should be ok.

How do I change the coil pack in my 2005 ford taurus

Welcome to Fixya.

Here's the procedure how to replace the ignition coil pack of your car.

Understand basic safety procedures. Any time you work on your Ford Focus, you should set the emergency brake and disconnect the negative, or ground, cable from the battery. Some mechanics recommend you isolate the cable to prevent accidental contact, which could spark a connection.
Release the spark plug wires from the Ford Focus ignition coil pack. You may need to pinch or press a release to unlock the wires.
Use a socket set or a small wrench to unbolt the ignition coil connectors. You also need to undo the capacitor electrical connectors. As you work, make note of which connectors go where--this pays off you when you reassemble the parts.
Locate the bracket that holds the ignition coil pack and the electrical capacitor in place. Undo the fasteners that secure them.
Separate the Ford Focus ignition coil pack from the mounting system. Replace the old Focus ignition coil pack with a new one. Verify the new ignition coil pack works with your engine, even if you use a universal ignition coil pack.
Reassemble the parts. If you have a Torque wrench, use it to tighten the ignition coil bolts with 7 inch pounds of torque (10 Nm).

Thank you for using Fixya!

Hi,i really hope someone can help?? ive got a 2001 ford mondeo 2.0i, ive got a misfire on 1 and ive put a new coil pack on with new leads and spark plugs and its still the same....ive...

The problem could be in the injection control module. This can be checked by what they call a noid light that can be purchased at a parts house, plug it into the injector pigtail start the car and see if the noid light comes on when it is supposed to fire on that injector if does not then the control module is going bad.

Engine missing, car jerking and juddering

you might have a bad plug wire it doesn't have to be loose you could have a hole or cut in the wire and it's not getting a good spark to the cylinder. the radio interferance tells me this might really be the problem
