Modus 1.4 limp or not?

Hello expert Elf's.

After doing some research I have discovered similar posts, but not the same.

I start the vehicle in the morning and drive for about half an hour on open road with not much traffic no problems power acceleration all good.
I come to a bottleneck on the freeway where you are forced to standstill.
Watching the rev counter, it suddenly drops by 200rpm within 15 seconds.
When trying to accelerate again the vehicle coughs, splutters and backfires when changing gears.
When traffic has resolved and the vehicle is still in this state once the accelerator pedal is pushed flat against the floor all the power comes back and that is the only drive-able position on the accelerator.
I you carry on for 5min or so it clears and the idling revs come up by 200rpm and the whole accelerator pedal is available again.

In a nutshell, if you keep the vehicle above 1500rpm it will never go into this mode, but if you start to idle then within 20sec it comes back.

What be the thoughts on this one, is this limp mode or not?

Many thanks

Check your throttle body is not dirty....

One of the most wonderful things in life is to wake up and enjoy a cuddle with somebody; unless you are in prison.

Re: Modus 1.4 limp or not?

Thanks, I already did that, it was very dirty. Sprayed it out with carburetor cleaner.
I have a 2l Scenic, on that vehicle I took throttle body out and even opened it up where it is is factory sealed and found the mechanism on the inside was also very dirty, just have no idea how the dirt gets into the sealed unit.
Maybe I should open up this one as well.
