My E34 Jerks at around 100 - 120 kmh when accelerating

Hi sifus out there, My M20B25 Auto suddenly started jerking at btw 100 -120 kmh when I push to accelerate, but if I pick up speed slowly - no jerk. Not sure what's problem but my mech thinks it could be the air flow sensor, plugs or even the air filter. Told me i could still use it though. Planning to get it done next weekend. Any of you guys might have had this problem and any solution to this. Thanks

Thanks bro,

I guess we can get the ori plugs at Bavarian Auto ? When you mean ori, BMW itself or they have Bosch, NGK and so on......

I think I m using NGK now.
