GT350 stutters at low throttle

[MutterTheresia]

Hello guys, I've had the following problem for a few days. If I accelerated at full throttle and then drive with very little so that I slide, then the engine stutters and stutters. As if someone were operating the gas themselves. If I go off the gas immediately at full acceleration, he abruptly takes the gas away from me. Have any of you had similar problems?

thanks

Failing throttle body?

Sounds very unusual. Do you have access to a code reader? How old is the car? It's tempting to think that the fuel filter might be plugged.

Are you saying that the engine is misfiring? My 2016 off and on had a slight and periodic engine vibration at idle like it was stumbling slightly.

Or are you saying that the engine is operating at higher RPMs for a while after you push in the clutch rather than going immediately back to idle RPM?

Thanks for the fast reply and sorry for my language. I live in Germany.
My GT350 is a 2017. The gasoline filter was changed 3 months ago. What surprises me is that I have full power at full throttle, but as soon as I switch to 5 gears and want to drive at a constant speed, he stutters briefly. As if you pressed the gas several times in quick succession.

If what you mean is your car:

- transmission in 5th or 6th gear at highway speed (example 100km/hr)
- engine has small interruption of power

Then you may have a bad transmission output speed sensor. Check if your cruise control is not working or works only sometimes. If your car has all of these issues then most likely is a bad transmission output sensor.

Hello TDC,
I noticed exactly the phenomenon yesterday. Sometimes I could not activate the cruise control at all. When he didn't stutter and I was able to activate the cruise control, he went on briefly. As soon as he stutters again briefly due to slight acceleration, the cruise control stops. It's really strange. Because when fully accelerating everything is fine. But why doesn't the engine light come on. Then at least an error would be written. What can I do if it is this sensor?

Here is the TSB on it

Thanks a lot.
I will show this TSB my Ford Dealer in Germany. I hope it works.

This morning I first disconnected the car from the battery for about an hour so that all possible errors and PCM data are deleted. So that the car is learned again. When I was driving in normal mode everything worked so far. As soon as I accelerate strongly and then want to go into a higher gear to cruise, he stutters and I can't get the cruise control switched on. if I press it several times I get it turned on at some point but then the vehicle jerks briefly and it jumps out again.

if this sensor is defective, should my engine light be on?

In the TSB it says that there is no DTC with this condition, so probably no engine light?
