On approach into MPTO ATC slowed us to 250kts; but this left us high. I fully configured to gear down flaps 30 and ref plus 5 at 153 knots. At localizer capture with the autopilot and autothrottle on aircraft banked hard for the localizer and lost a headwind component which slowed the aircraft below ref with a momentary stick shaker. I disconnected the autopilot and advanced the throttles and continued the approach. We flew a stabilized approach; but in the flare gusty winds caused me to add power at touchdown--the aircraft hit the runway and skipped so at that point I did a go around; and returned to an uneventful landing.
On descent into MPTO we were left high by approach control. Once descent was given for the arrival we were also assigned 250 kts for the speed which also made it hard to get down onto the proper path since we were not able to descend at 280kts until 10;000 feet. We were eventually assigned the RNAV ILS 03R approach and we continued to descend via the published procedure. Although we were still high; the captain did a good job of getting the plane configured early so we could get slow and rejoin the path. Before the base turn onto the Localizer for 03R the captain had the plane fully configured and at ref plus 5 kts for the speed; with the autopilot engaged and auto throttles on. As the plane made the turn onto the Loc (approx 2;200 feet); I was running the landing checklist and looked up to notice that the speed was bleeding down. We were about ref plus 2 when I noticed this and I vocalized 'airspeed' as the plane was at ref speed. At this point the Captain responded to my call out and increased the throttles manually and kicked off the autopilot to correct. The lowest I noticed the airspeed was ref minus 5 before the speed began to trend back to the target speed. I never noticed the stick shaker go off on my side but the Captain mentioned he might have gotten one small shake as he recovered. After the recovery we continued the approach onto 03R. The rest of the approach was configured with just some bumps. We were on target during the approach and landing but a firm touchdown caused the plane to bounce back into the air. Once we bounced the Captain elected to go around and we flew the published go around procedure as directed by tower. We were vectored back around for the ILS 03R approach and landed safely with no issues.
B737 flight crew reported on airspeed difficulties on the ILS; followed by a bounced landing and go-around at MPTO.
