Haha no I can’t use phone and drive, I’m a safe driver, don’t do silly things as I’m a worrier. Yes will tell mechanics not to throw out my sparks. You know what I’m either going mad or making up a memory but I think my engine used to have a plastic top cover and I don’t have a clue which garage has got it as it’s been to lots in the last year or so. Oh well if there was one it’s gone forever now. 

And has caused you no trouble nor inconvenience. Sparking plug  condition is like an MRI scan to people who understand engines. Good pictures are a big help to tell us if the problem is in the engine or elsewhere. Your steamy exhaust is quite normal on cold mornings. How far do you drive it in the morning?

What fuel are you using?

Super fuel may be too rich for it, if it's not mapped for it, it will never learn, just run too rich.

Make sure air cleaner is clean and dry and MAF sensor is clean

Normally, on a fuel injected car, if you can smell fuel it's because there's a leak

Hi everyone…I’m back again lol 

So I had it serviced early feb. Ford plugs, filters and Castrol oil. Oil engine flush was done and engine additive added via petrol filler a good branded product by indie garage mechanic. 
Filled tank to brim and refilled since and made a note of mileage. Calculated 550 miles out of £100 of petrol. My tank is meant to hold 42 litre £60. 
I don’t drive far so I’m guessing short journeys bust car.
No fault codes still. Mechanics not interested in looking for leaks or testing sensors so I gave in and it’s been to a local Ford dealership last Friday.
The rattling tinker tick noise had gone very faint. But used to be very loud and sometimes quieter. Mechanics didn’t have an answer apart from one diagnosed grit in tyres 😂

From my list of symptoms Ford said it was camshaft timing and PCV valve. So hundreds pounds later on Friday afternoon the engine was stripped and camshaft was adjusted. New gasket seal. Engine still sounds the same it doesn’t purr but I haven’t heard the rattling tinker tick noise. 

RPM on start up hovering over 1100 like it’s open choke trying to adjust. Settles to 750-800 warm. No change to before having PCV replaced.

my Cheap plug in OBD was previously showing negative ADV spark, negative short term fuel trim between 0 to - 8ish and longterm moved around positive and negative. 
Drove back from Ford Friday tried OBD closed loop engine warmed up and still have negative ADV spark. Is this normal ?
STFT is now positive under 10 

LTFT is now negative under 8.6 so the LTFT has changed from moving around to staying in low negative numbers. 
I know an old car won’t be zero fuel trims. Would be good to get closer to zero. Are the trims normal ?
does anyone have any ideas?

I have read that negative LTFT isn’t usually a leak ?

I’m taking it back to Ford to ask again about RPM. Ask about manufacturer specs because they thought the camshaft timing and PCV would fix the RPM and symptoms.

Sorry all another long story description.

am I chasing a RPM fuel ghost ?

For future reference, you really need to measure fuel consumption in MPG. That way you can compare any improvements of consumption, or any worsening. Price of petrol changes weekly, so using '£' as a comparison is futile. 'Miles' & 'gallons' are constants...

Hi

my mpg varies depending on journeys 

it can go down to 24 and best I get is 31 mpg. 
manufacturers range is unrealistic. 498 miles a tank, if only.

As you have discovered, the only true accurate reading of fuel consumption is to brim it, and calculate usage at next brim. No car computer is as accurate...

Hope someone can help with your other issues...

That’s the problem because mechanics say high RPM is normal on cold starts. Ford thought they would fix it so I’m confused if RPM is a problem. Conflicted opinions. But my reading research suggests RPM isn’t normal. I want to ask Ford for spec manufacturer details. I would try cleaning the MAF sensor but don’t know where it is. Is it inside the throttle Body? Can’t find engine component layout diagram for petrol mk7 fiesta

On a cold start engine, I would estimate the RPM to be about 1100/1200 RPM, once warm, it should drop to 800/900 RPM

Yes it was 12-1300 but engine vibrations through steering wheel. It’s slightly lower and less vibration. Warm sits under 900. Ford difficult to ask questions via phone can’t speak to technician. Wish I could have confidence and skills to test sensors myself but I don’t know what’s what. Bought a voltage meter reader but indie mechanic told me off says too dangerous but then they haven’t done much to help lol they didn’t diagnose the camshaft noise. 

Some engines have the MAF sensor clipped ontop or on side of the throttle or air intake body ? I can’t see my maf sensor 

I don't believe you have a MAF sensor. Some vehicles have a MAF, some have a MAP/TMAP and some may have both. My focus has a TMAP, no MAF. Note in your own pictures of your scantool you have a MAP reading of 29kPa, but for MAF it says N/A. The sensor on your throttle body will be your MAP/TMAP.

Thanks yes I googled and thought so. So when I had a throttle body limp code 2 years ago it could have been cleaned by Halfords as they said they cleaned throttle. Refused to replace it under AA warranty plan. Because it was £500 Bosch. And didn’t know if it was the throttle pedal sensor. Is 29 kpa a normal reading? Thank you to everyone replying 👍

Is this a 1.0 Ecoboost?

If so, get rid of it, quickly, you've just added engine flush at the oil change, this will degrade the wet cam belt.

Count the plugs, Dave.

Never knew they put a V16 in the Fiesta myself! 😮

Oh yeah🙄

Hey guys what you mean it’s only 4 spark plugs 

Ford and indie garage said it’s due for belt and water pump change. Need to get quotes. Ford said take it in Thursday because I don’t think changing the pcv made any difference to the RPM. 
you say get rid of it but could end up with a car with faults so it’s another risk. 
Ford passed my car back to me without checking RPM on cold start and I’ve no idea if they used the diagnostic scanner to look at live data before and after the jobs done. Ford probably going to try charging for guessing the parts ?

You posted 4 x pics of 4 plugs - 4x4=16

That comment was made (to get rid) when the assumption was it being a 3 cylinder ecoboost!

Haha I put pics of all angles to show the carbon. Well I think it’s drinking fuel like a pick up truck. Ford said belt looked ok for now but advised £400 -£800 car is 10 years old now only 55,500 miles. Surely fuel economy is off. Filled to brim, let it go half way filled again. £100. Petrol light flashed today on 50 odd miles range left. I photographed mileage clock so I deducted miles so I’ve done 520 miles.    Roughly 29-32 mpg. My daughter had a Toyota aygo she could get 450 miles from a full tank about £45-£50. 
Oh I think I can still feel a slight vibration a small wiff of fuel or exhaust don’t know which. Any ideas how to discuss with Ford Thursday what to say ?

I still don't know why you insist on using 'money' as a measure of fuel consumption. Now, does your daughter pay £1.30/liter, or £1.85/liter? See what a nonsense that is?

Are you saying it has cost you £100 to fill half a tank (approx. 22.5 litres)? Blimey petrol is very expensive where you live.

As others have said you will only get an accurate measure of fuel consumption by filling to brim, driving until near empty, and then filling to brim...fuel put in and miles between fill ups will give you the actual fuel consumption.

In my ecoboost Mhev I'm getting upper 50's mpg...!

I’m curious to know how many miles at worst a 1.2 fiesta should get from a full tank and if my car has a fault because no codes. But has had symptoms for ages. Ford said RPM needs looking at again. I’ve no idea what they will or won’t find. They said it was this pvc I have no choice but trust the mechanics. I don’t know what’s what. Don’t mind paying repairs if it’s not guesswork. It’s either pay or find 10 k plus for a second hand 5 year old car.

According to Google, you have a fuel tank capacity of 42 liters = 9.2 gallons. It also has a EPA combined MPG of  54 MPG. Sorry no money involved, I only deal with accepted universal constants...

At 9.2 gallons of fuel, and at 54 MPG, that should go 496 miles before stuttering to a stop.

This may also be of interest to you - stats on actual MPG for your car...

(Of course, Google may have offered the incorrect capacity! You may get a more accurate figure from your owners manual)

Lucky you Martin. Won’t get 50mpg out mine. I think the esso supreme is around 159 to 169 a litre in my town. I stopped using the cheap E10 last summer because it seemed like it was vanishing. Just curious if 1.2 petrol fiestas get high mpg. Daughter had a 1.2 Ford KA which was good on fuel and the aygo was very good. Ford thought their repairs would help but pcv made no difference.
