Narrative:

In trail behind a 767 heavy [we] entered his wake on the dobbi STAR. Severe enough I turned off autopilot to reestablish level wings. Requested to be vectored off the STAR due to B767 wake. Vectored off and given a turn to intercept final. I could feel the aircraft on the verge of entering wake again. Cleared for the approach but I managed it with localizer and vertical descent to stay above glide slope to avoid B767 wake. I thought I heard clearance to hold 170 to kerns. The approach was active and confirmed but for some reason the auto throttle allowed aircraft to slow below ref speed. The autopilot was off at this point. I advanced the throttles and turned off the auto throttle to spool engine and regain speed.became very tasked loaded trying to avoid the B767 wake. [Suggest] more separation from heavy aircraft.

Title: A319 Captain reported encountering wake turbulence on approach to IAH in trail of a B767.

Narrative: In trail behind a 767 heavy [we] entered his wake on the Dobbi STAR. Severe enough I turned off autopilot to reestablish level wings. Requested to be vectored off the STAR due to B767 wake. Vectored off and given a turn to intercept final. I could feel the aircraft on the verge of entering wake again. Cleared for the approach but I managed it with LOC and vertical descent to stay above glide slope to avoid B767 wake. I thought I heard clearance to hold 170 to KERNS. The approach was active and confirmed but for some reason the auto throttle allowed aircraft to slow below Ref speed. The autopilot was off at this point. I advanced the throttles and turned off the auto throttle to spool engine and regain speed.Became very tasked loaded trying to avoid the B767 wake. [Suggest] more separation from heavy aircraft.
