Jerking while accelerating in 3rd gear

[johnhalton]

Hi!

Brand new on here and some really interesting threads that have helped me already but wanted to get thoughts on the problem I’m having.

In short, the car runs great 99% of the time - recently had carbon clean, new injectors, new MAF sensor, new spark plugs, throttle body cleaned.. as maintenance I planned to do after buying the car about 2 months ago.

However, it’s jerking occasionally under semi-hard acceleration in 3rd gear (only noticed in 3rd gear anyway) - and it’s annoying.

Seems very variable when it does it, has done it when cold and after being driven for a while - and I can’t always recreate it even directly after it’s just done it.

No fault codes showing when the dealer have tested it and driven it with live data (all be it they’ve not been able to replicate it)

Any thoughts? Best guess so far from other comments is maybe a coil pack on its way out.

Thanks in advance!
