Hello i have a problem with my rb25de neo. It's and auto but i genrally use the semi auto the drive but the problem is that after i get up to 3000rpm. In second gear then change to third and will have a spot where it drops right back down to like 2500 and after a second it picks back up again.To where it should be and it's 5 times as worse if the aircon is running and it will happen even if you change at 2000 rpm. Im totaly stuffed about it i got cam cover gaskets and new spark plugs recently.I thought i would ask on here first before i get my mech to look at it maybe a simple fix?.
Cheers!
