this is something I noticed lately. when i drive slowly - gear change at 2000rpm all is good, but when I take it to 3500 rpm after gear change revs falls down another 200-300 rpm ( down to 2200-2300 for just a second) before settling at 2500rpm?? oil and filter done aboout 5k ago level checked and is ok. any idea what is causing my problem?
