Power dip at 3rd gear

[Ade]

I'm currently experiencing a sudden power loss while accelerating in 3rd gear between 2500 and 3000 rpm. The car jerks for a moment with a rpm drop of about 150 rpm. My car is an 325i M54B245. Tried the following but no help.1. Changed fuel filter.2. Cleaned Air Filter, MAF, DISA and ICV.3. Checked spark plugs.4. Cleaned ignition coils.Any other ideas? Please help!Thanks!
