Bored of months of stalling issue. HELP

   Gonna just go all out and explain it all.
   
   Stalling issue out of nowhere at least a month or two ago. Car revs very low below 1k rpm. Even when changing gear the rev counter just drastically and quickly drops wanting to stall and will if you dont put it into gear quick enough. This is an infrequent problem. Sometimes the rpm will rev high and nice, rarely though. Thermostat changed, ICV cleaned, GASKET CHANGED, rocker cover done, temp sensor changed, engine mounts replaced. Only thing I'm waiting on doing is swapping my manifold as it is badly bent... Could this be the cause of the infrequent stalling? Seriously hoping so... No one seems to know what it could be and starting to seem like ive tried everything. It's at the point sometimes where every junction i come to a stop at, my car will stall and I need to keep my foot on accelerator in neutral to keep it alive........
   
   Sometimes turning it on the rev counter doesnt seem to activate, then it catches itself up and starts. Could be an ECU issue? Want to try everything first...
   
   Any comments suggestions or anything is greatly appreciated.... Tried a lot so far.

   Summed up, my car isnt idoling.... Just stalling. Making it really dangerous for me when driving in traffic cause every time i need to put into neutral and stop at a junction its stalling unless revving it or still rolling in gear...

   What about buying a brand new icv? You might aswell try it seen as they're less than £15.

   I'll put money on the MAP sensor needing replaced.

   Alright mate thanks. Gonna order a new ICV and MAP sensor... With any luck when I fit the new backbox and 421 mani it'll be sorted..... hopefully...

   Open to other suggestions in the mean time. If it's cheap parts I'll likely do it if I haven't already as I need to order the other bits. That's how desperate I am now to get this fix done lol just throwing money at it..

    What you're describing is MAP sensor failure all over, they aren't expensive, even a Citroen one is under £40 if I remember correctly.

    Thanks mate. There's a dealership across the road from where i work now. So I'll pop over once I finish and get quote on the MAP and ICV

    only other thing I can suggest considering, is the coil pack.
    
    If this is going, you'll likely have some mis-firing at times as well.
    
    Another tell tale sign of the MAP sensor going, is sometimes under part-throttle, it will hesitate, and seem like it's mis-firing, and clear immediately under hard throttle.

    check inlet manifold for air leaks,split rubber pipes, missing hoses etc

    All I will say is that when I previously ran it on a scanner (not that they're always entirely accurate) it came up as air filter but nothing about map sensor

    Anyone near you or a mate got a VTS? You could slave in the MAF to confirm it?

    Unfortunately I dont aha. ICV came yesterday , hopefully map today then just waiting on 421 mani and back box, will get it all done and report back on here if problem persists after.

    I read somewhere the other week about a "turn off and on test 6 times" which I tried the other day. My car now seems even more damaged and is stalling harder and struggling to stay alive even neutralled feels slightly struggle and turning on sometimes nearly doesn't start needs revving again or will turn over then stall 😢😂 my advise don't try the "turn on /off engine 6 times test whatever it is or is meant to correlate lol

    Now stalling at every junction I put my clutch down at unless I rev. Also I've noticed this weird noise that keeps occurring. When I pull off, it's a weird screeching noise, as if I'm putting my foot fully down and wheel spinning. Happens once briefly then stops. Could this be my altenator belt?

    Could be a fuelling issue, is your car misfiring at all? If not try your coil pack

    "Misfire is a common driveability problem that may / may not be easy to diagnose, depending on the cause. A misfiring cylinder in a four-cylinder engine is hard to miss. The loss of 25% of the engine's power output is the equivalent of a horse trying to run on three legs. The engine may shake so badly at idle that it causes vibrations that can be felt in the steering wheel and throughout the vehicle. The engine also may be hard to start and may even stall at idle, depending on the accessory load (air conditioning, headlights and electric rear defroster, for example)."
    
    Ok reading this, yes I have every single problem listed above there atm lol. Shaking is insane but I put that down to my bent manifold? Also the loss of my baffles on backbox and the manifold being f'd i put down to 25% power loss?

    If anyone gets a chance to take a look...
    
    Second half of issue is basically the problem that occurs every time I come to go into neutral at a junction lol.

    Have you fitted your new ICV, and cleaned the throttle body/hole where the icv sits?
    
    How does it drive on throttle? hesitating/stumbling at all?
    
    Serviced the car at all? spark plugs, filters, oil etc.

    I used to have a rough idle and stalling issue.
    
    Changed every single sensor you could find.... only to find out my exhaust manifold had a hole/ crack in it... causing a faulty reading at the lambda sensor.
    
    list of things to check...:
    
    - ICV
    - MAP sensor
    - crankshaft sensor
    - coilpack
    - spark plugs
    - Vacuum leak in the system (check hoses for splits)
    - check hoses going to the carbon canister
    - fuel filter
    - temprature sensor??
    - lambda sensor/s
    ...
    
    have you tried a code reader?? eml on??

    Well this is the thing I'm hoping it is the manifold really. It has been an ongoing problem for some time and is way overdue to be done. 3 of those other things have been ticked but once mani is done if I have further issues I will try some of them out. Praying its the mani tbh have been all along! Thats reassuring info. Cheers for other possibilities all useful also!

    Was serviced not long ago with new sparks! Sometimes throttle can hesitate when pulling off, or feel very joulty in first gear despite the power loss. Throttle body/old ICV was all cleaned up looked ok but I know ICV is kinda on its way out anyway as sometimes on occassions it will rev really nicely almost too nicely... Say around 2k. Very infrequent problem that though. Still wondering what this screeching noise is that sometimes happens when I'm pulling off (slowly or normal speed) though. As if wheel spinning but obviously am not. ICV and MAP both to be fitted very soon.

    EML not on. Previously went on scanner which said air filter issue lol so not sure on that. My mate knows someone at dealership tho gonna try get some proper codes for it next time I see him. last scanner prob wasnt citroen specific

    get that new icv, and map sensor on buddy!, I bet you that will fix it, failing that, try all of the above ^^.

    Kind of embarrassing... But there was a snapped bolt in one of my engine mounts (shit job done on it by someone who replaced the mounts but put one of the snapped bolts back in....) So fixed it up and its ran amazingly ever since...... Still slighty hesitation and drop slightly below 1krpm sometimes when coming to junction stop, but nowhere near as bad. Runs so unbelievably smooth in comparison to what it did as engine was sat on chassee.... So you can imagine. So nice to drive now. If it does get progressively much worse again with stalling/starting/revs then I'll have to sort map and icv. But for now it seems much better although not 100%, about 95
