Issue with engine choking at 3500rpm

Hi all,

I had an engine performance issue where the car cut out - presumed it was the intercooler hose from the throttle body (the short one) however, I have changed this for a silicone one and intermittently the car jerks when it hits about 3500rpm and then carrys on.

Could it be another intercooler hose or is there something else I need to look at?

I have checked and there are no fault codes showing.

Any suggestions would be very welcome

TIA
