Honda jazz 2007 automatic idle to drive problems

[Haz]

Hello! I am new here and at my wits end with my lovely Honda Jazz 07 automatic.  :'( when my car is rolling it drives, starts fine. But when I’m idling in traffic or moving from neutral to drive, my rev count goes right down and the car has stalls! I’ve since changed all fluids (correct fluid on engine and auto transmission) changed spark plugs cleaned the coils cleaned the torque valve all with no avail. My car hasn’t stalled since changing these things but my rev count drops then something thuds and it goes massively up like I’m pressing acceleration, when I have my foot on the brake!! I’m at the end of ideas, all mechanics just say it’s bullet proof, which is great but my car is not running right! Please help!!

The forum will help with more info, how many miles since these issues arise?
What happened immediately before this problem?
How long owned last serviced by garage?
Stop spending £ get a local trade block diagnostic check to provide data.

It has done 150,000. I have changed fluids recently but fluids haven’t been changed for a while before that.
Not much really other than hesitant on pulling off, car takes a while before it decides to move.
Diagnostic was done in garage and they couldn’t find anything.

There are two key things to  do (and any competent garage would do them)
Clean EGR valve
Clean MAF/MAP sensor

Neither gives error codes but if dirty will give fuelling issues.

This is basic grade 1 mechanics: your garage are incompetent,

The above are easy to do so cheap.
Then at the mileage the valve clearances may have narrowed so check and adjust,   - can call hesitation at low speeds but no codes.  Takes  time so ££s

Check the PCV valve. Easy.

There is also a tinny noise when accelerating. MAF was checked and EGR was cleaned and checked. Apparently no issues.
What I find hard to come to terms with is, how does none of the mechanics I’ve been to, do not know what the problem is!!! It’s so frustrating! Driving this morning was doing the same thing again! But settled slightly, no doubt I’ll drive home and it will do the same again. All I’m being told is to keep revs up 🫣 I appreciate all your replies so much

I think that I have the same thing on my 2007 Jazz CVT.
Please note this is nothing to do with the infamous Jazz Shudder.
When I first start the car, when it is idling, the revs drop and it starts to rattle as if it's about to stall.
This is with no touching of the pedals.
It never actually stalls but goes through all the motions as if it's about to.
After the car has warmed up it sporadically does it when idling.
It tends to do it when reversing even when warmed up.

Did you find a cure?

I also have the same issue,  although mine has never actually stalled. But I am sure that it is related to the judder which I also get around 10 to 15 mph each time I take off from a standing start.
Mine is a 2004 SE model with 81,000 miles on the clock. I have changed the fluid, replacing it with the F type, which made no difference at all. I bought the car 1000 miles ago, knowing it had the judder, but I thought that after all these years there would be an upgrade kit available or lots of knowledge around to repair / replace the parts causing it.
8 years ago I bought an old Volvo with problems which were well documented on the forums, along with instructions and often videos on how to fix them; I am surprised and rather disappointed.

Has anyone on here stripped and repaired a CVT? Has anyone had a garage successfully repair one, and can recommend them? I see so many about that I can't believe that they aren't fixable. There are YouTube videos of people in the far East stripping them down without any special tools, and there are lots of used ones advertised,  so one could rebuild a used one and then just swap the two.
Someone must have a procedure for this.

I had similar problems of stalling. Loose spark plug and faulty coils. Car was at 145k miles. After tightening the plugs and replacing coils with used low mileage ones, car is running fine now at 152k
