HI, I've recently brought a 1.8 duratec mk2 Ford focus with 46,000 miles on an 07 plate.

I love the car but just a few things which I want to sort out.

At low revs when accelerating there is what sounds like a slight pinking noise from the engine, is these quite common, the air filter and spark plugs are new.

Also when driving there is a faint knocking from the drivers side front when going over uneven roads. Top mounts?

When starting car from cold the belt is making a squeaking noise untill the car has warmed up. Are these stretch belts fitted on these? And is the tensioner common to get noisy?

Thanks for the help!

Hi Martin,

 

the pinking noise could be due to a slight misfire, the spark plugs may be new, but did you replace the HT leads also? the coil pack may be on its way out, but replace the HT Leads first.

 

The knocking noise could be the top mount, but it could also by the CV joint.

 

As for the squeak, the tensioners have been known to go, it would be worth having these replaced if the issue persists, but it sounds like at least the bearings are on their way out.

It doesn't have leads just has four coil packs. Doesn't feel like it's misfiring, unless it's the tensioner making a noise similar to pinking. Are the belts stretch fit ?

I believe they are none stretch, but cant swear to it, but unless I am missing something, you still need a way to get the high voltage spark from the coil pack to the spark plugs, so you should have some for of lead gong from the coil pack out to the spark plugs?

Thanks I will fit a belt first as a squirt of wd40 made it go away. The lead looks like it's built onto the coil pack.

have you got a photo?

 

I am not overly familiar with the engine you are referring to but perhaps someone else could clarify where I may be going wrong!

OK so, it sounds like there is something wrong somewhere on the wiring harness, I bet its related to the sensors (one or multiple). I expect that the relay and ecu connector are not getting all of the appropriate values, and so the engine just uses default values rather than accurate realtime ones. I wonder if its misreading, or not putting the right amount of fuel in for the actual amount of air that there is in the system, thus causing the knocking. It could be a bad lead, bad connector, bad sensor, its difficult to say.

 

How new are these sparkies, and if they are all built into this system, where they all replaced together, as it looks like one loom, one unit?

 

Did you replace just the coil plug in units?

Yeah sounds possible, but I'm not 100% sure it's actually pinking or just something that sounds similar, maybe the tensioner it's not thatbad and only intermittently. There are no faults might give the o2 sensors a clean and the maf sensor if it has one.

definately worth a try, and check if it has any error codes if you can (where are you in Kent? - I might be able to help with reading the codes if you need it?)

Thanks for the offer, I have read the faults with my torque app on my phone and on the cluster and showing no faults. I'm in west Wickham. Trying to find locations of components on this engine is a nightmare!

not sure where that is, lol as I am a northern boy at heart, I know my way around most of medway, and down to ashford, anywhere else is beyond me lol.

 

The Torque app only queries the instrument cluster and the general repository for error codes. I have an airbag light on, have had the Cruise control disconnect itself once or twice, along with an immobiliser error (chip in key broke!) Torque didnt pick them up, but I have a modified ELM cable and FORSCAN on my laptop which I used to scan all the modules on the car and that gave me all the errors. It gave me a lot more info!

 

Torque is good, it accesses a lot of live data but it is generic along with the bluetooth, whereas tools like ELM and FORSCAN are more designed for the Ford, Mazda and similar ranges, so knows which modules to ask which question, rather than asking generally what errors might be in the central repository!

I downloaded a Torque add on to monitor detonations, and its coming up with possible detonations. I know its not accurate but its probably is pinking then, might put in new plugs or clean the coil packs out and I don't think I noticed it before replacing the spark plugs. I fitted the correct iridum NGK spark plugs.

Does anyone know what the gap should be on the ngk ITR6F-13 (4477) as I want to remove them and check the gaps are correct. Thanks
Also does anyone know what make of plug does ford use?

book  says 1.3 I believe but its the 1mm gap that makes it work correctly as far as I know....
