If the flare is at those lower RPMs (only) then I think it must be the TPS (right, svx_commuter? ) I took mine off to clean but it didn't seem to make much difference; I should probably soak it in contact cleaner (instead of just spraying it in) and maybe readjust it. The easy thing to do is just drive, keeping the RPMs right around 1800-2000 under acceleration (seems to be the best range for a better 2-3 shift anyway)
