This photo was not from a Felicia, was just for informational purposes.

I use toothbrush and paintbrush with hog bristle to clean this item, many times some dust or residues does not let it close properly so more comes in the the idle is not as it should be.

 

@Joob : Have you ever tested a small hose attached to the front of the pressure regulator?

If that is not pushed front properly and it's loosen or damaged then you have an unstable idling because your vacuum does not work properly.

I suspect a vacuum leak or the throttle body needs cleaning and reset.

cleaning yes vaccum leak nooo, leaning will cause the idle to surge upwards

For cleaning take a look at my detailed video.

It depends of the size of the leak and other variables.

The way that the needle moves up and down for me shouts ''throttle"

You should clean the central part of the throttle much better (i suppose you use cleaner spray) and spray contact cleaner to the plug of the throttle and as the cover is out spray some WD-40 to the accelerator wire.

 

Your air filter is in good condition?

12.6 V are with cables on and key off or just without cables as is in the shelf?

 

I'll clean up better, and test and see the result.

Yap, 12.6v with cables on and key off.. and without cables it's the same.

The throttle body is not too bad but if you do want to clean it use the correct cleaner for cleaning throttle bodies. - (Scotty Kilmer) Make Your Car Run Better with a Little Spray Cleaner - 

 

ETA: perhaps your throttle body and plate are dirtier than the photo shows with muck built up behind the plate making take up and shut down from idle unsteady. 

 

 

I'll do that  like this

12.6v is good but is that off the two battery posts, if so what is the reading from outside of positive post clamp to a good earth point on the body(?) - BUT - your car starts fine in the first video, you revved it up too soon, leave it to settle itself or just drive the car off normally.

 

Your battery terminal clamps look like they might be sitting a little high on the battery posts and that is why the clamps have been bent and overtighten - BUT - that may have put a ledge in the battery posts so leave them as is.  And there is a glob of solder(?) on positive connector as long as the cable and connector are firmly fixed it does not matter.

 

Second video it sounds like you might be pressing the accelerator pedal with your foot as you start the car or just after, if the car is cold do not do that.

 

Unplug the MAP and then putting it back on may have just upset the ECU working out the fuel and air.  I am not a mechanic but I can not see what doing this would achieve or prove and I can not see that it is generally a good idea to disconnect and reconnect a live electronic/electric connection but I may be wrong perhaps the ECU likes the off/on-again action for reset?  Seems a bit risky to me.

 

I do not see what the problem is with the tacho (rev counter) needle other than you are doing this well before the engine has fully warmed up (unless the temperature gauge reads too low). On second thought - perhaps your throttle body and plate are dirtier than the photo above shows with muck built up behind the plate making take up and shut down from idle unsteady. 

 

There is a lot of dust on the engine - is your air filter clean or replaced and the air filter box and air intake all clean of dust and have you clean oil and oil fitter?

 

You could also clean the MAP sensor and check its seal you also want any pipes or hoses clean inside otherwise the dust or muck in them with mess up the sensors and filters you have just cleaned (or replaced).

 

Allow plenty of time for the sensors or other items to full dry before refitting them and do not leave them lying in muck or dust or where dust or muck can blow or get into them.

 

I don not mean anyone just a general observation, I see people cleaning items with dirty materials or in a dirty environment which can mean the items and not fully clean when refitted, obviously there is a limit to how clean but the cleaner the better, it is after all cleaning not re-dirtying.

 

 

 

Alright..

I don't think I was able to get the clamps down any farther, but I'll see this. That half ball of solder, was the addition of the cable of the starter motor that I had made, to see if it would improve the starting. (I was already doing this for a while).

It was right after I pressed the accelerator.

I think it's okay to turn off the MAP when the car is on, but I think I remember times when I used to do that, I think the car wanted to go down, I don't remember well. And now he did nothing. I managed to start the car without the MAP turned on and accelerated and it was ok.

The rev counter fell and rose, kept swaying slightly, it looked like it was going to die. Is it the cold engine? I don't think I should.

As a matter of fact, the air filter has never been changed since I have the car, but it was already a car that didn't move much, it belonged to some old people and was in a garage, but I'll check the filter too. The oil and that's all new.

I always clean these more sensitive areas with clean cloths.

That is the result wanted from cleaning . 👍  By the way I am not a particularly over clean type of person and am a bit scruffy but I do want the engine to run well which usually means clean supplies of fuel, air, oil coolant, etc..

kakaka good trick in relation to the hole. .. I know it's a example image.

Yap, works well without connecter

I think it would have to go down or choke when disconnecting the map sensor.

Pressure regulator where ?

Thefeliciahacker I have just had a very quick look at the start of your video and it looks like it will be very good and thorough and it is very good of you to make it to help others.  I did notice a couple of small points I could if you wanted me to PM you on and look at the rest of your video when I have time but I do not want you to think I am criticizing or that I could do the job or video better.  I am not a mechanic or have any mechanical aptitude or an expert in anything but very unfortunately for me, as I loathe working on my car, I have had to so have picked up a little experience and remember a bit from doing so 40+ years ago..

This is the very basic missed that should not be otherwise moving on with any diagnostics could be very flawed.  The air filter might be very clean but it could also be dirty and clogged from just sitting in a dusty garage or it could be clogged from insists and animals that used the housing and filter for various purposes.

 

On the Fabia Mk3 IIRC the air filter is only changed every 4 years but with the old cars I have had air filters changes are annually or 12k-miles but as the paper filters were so inexpensive I would often change at 6-month services.  To an extent the more air the bang.

I even have a KN in my car, but I'm going to check the filter on this machine.

May also not be getting enough air in for the mix.

Flood gates opened.  🤣

 

I will have a look tonight, I really must now do the washing up, clean the wheels I left too late to do yesterday and have a look at a neighbour's electric tyre pump, silly  wheezing things (with inaccurate gauge) I much prefer a manual foot pump (with inaccurate gauge), not that I have a cigar lighter or 12v socket in my car.

I have two in mine.  😁  They still sometimes ned cleaning and at the last rolling road set up all the red oil was blown out of them as I had over oiled them and the tuner said the airflow is better with them dry.  I tried a single overall K&N filter for the twin carbs but it was found to be very slightly better to keep the two individual K&N filters but a very large magnifying glass is needed to see any power figures on my car.  The specialist tuner I go to does not have or believe in the ego gauges and print-outs that many others seem to have.  I went to another highly recommended specialist tuner once and I could see his gauges were reading so "optimistic" that I did not bother with a print out, and he did not do a very good job of the tuning despite the length of time it took and the cost.

I think the K&N filters are very good, with better airflow, etc.. by chance I haven't cleaned mine yet, I'll take a look at mine 😛

What do you want me to see ? sorry..

 

 

 

Okay, I've already cleaned the butterfly properly .. cleaning the plug at the butterfly, I turned on the machine and it seems that it worked more correctly and that it no longer swayed.

Now I'm going to test it tomorrow morning, and see how she handles herself.

Every 4 years doesn't quite sit right with me, even for a newer car. I do mine annually as I left one for 18 months (or less, was serviced in October 2020ish by previous owner) on my Mk1 and it was choked to hell doing ~180 miles a week since my purchase in March of this year. Changed the filter and the sharp throttle response was an immense feeling, nearly launched it straight out of the driveway and into the house across the road.

Well doesn't that tell you there is a problem when there is sharp throttle inputs that require fuel enrichment

Joob, arse kicking time for you then.

 

Given this improvement you now might be more encouraged to look at (change) the air filter, and perhaps clean the inside of the air filter box and inside any trunking and inside any hoses for vacuum etc..

 

Much of servicing, maintenance and repairs just boils down to cleaning and lubricating, not sexy stuff I know but very necessary and something a master mechanic would start with which is part of the reason they get to that level.  Even with the computer electronics now much is electronically cleaning off error codes that don't relate to current running. 

 

Next I will want to see a photo of that butterfly fully open so that I can see it's totally clean on the rear side and shaft and body.  And next your boots or trainers  🤣

At the time I thought you could have put an arrow to it - but I'm much too polite to ever mention such a thing. 😉

 

[Joob]

Now the throttle I think it's ok

Haven't been making that oscillation. 

[Joob]

Today in the morning, I tried turn on the car and I couldn't.

Only when I push the car to go down or on the straight, I get into it, engage the 2nd gear and it turns on. dammm

 

Check when I tried turn on in the morning.
