[Engine] Parkinson Mode

[gonzo2227]

Hi, everyone,
I have a strange problem lately, between 70-100 km/h the car/engine shakes wildly unless I press very minimally on the gas pedal.
This also happens when there is a positive slope on the road.
At low speed on the plane the problem is almost non-existent
Feels like the engine is struggling to give 'power' between 70-100 km/h and uphill. Above 100 it more or less disappears.
No engine computer related issues
Does anyone know what the problem might be?

The fact that you can 'accelerate' through the problem in that it disappears at higher speeds makes me think it isn't necessarily an engine problem?

Out of balance front wheels??
Maybe a bad engine mount??

That's made me gut laugh Parkinson mode

Imbalance in the drive shafts?

Now that I've recovered from the Parkinson's monicker, the fact that the issue you have seems to change at a given speed, and with gentle throttle control does not amplify the problem, I'd say loose engine mounts are a highly likely possible cause. I've had exactly that same symptom from my transit connect a couple of years ago from a sheared engine mount.

Engine mounts - my 2.0Hdi does it. I have a thread on here about it but it's effectively mount rubber is too soft, it's fine in winter but starts juddering again when the weather warms up.

I've changed all mounts including a PU rear bush, still does it.
Use a lower gear and a few more revs.

After doing quite a bit of research, the most likely thing seems to be the turbo,
It happens under load probably when the turbo opens, but not pushing enough air, so there is too much fuel in the engine
Does that make sense to you?

I like the easy approach first ..... give the fuel a hefty dose of injector cleaner

Give it a week to run through and see if it solves your issue.

Don't laugh you may find it works ..... I used to get a regular " anti-pollution " fault whe driving in town and giving a regular injecotr cleaner dose sorted that for me.

SOLVED

It was the control arms, after replacing them and the drive shafts - the problem was solved.

Thank you all ?
