Weather
On approach Into New York's LaGuardia airport; Runway 31; we experienced a wind shear event that caused a go around. During the go around we were assigned an altitude of 3000 ft. Upon reaching 3000ft the Captain asked for me to request a block of airspace from ATC because we were struggling to keep proper pitch and wings level attitude in moderate turbulence. Due to workload and ATC congestion I was unable to make the request and one updraft ballooned us to an altitude that was approaching 3200 feet. Once we got to a higher; and slightly smoother altitude we handled the bleed one over pressure that had occurred at application of max thrust during the wind shear event; and assessed the situation. We thought it best to divert to JFK for more favorable conditions. We landed uneventfully.
We had shot 1 approach and tower called the go around. The aircraft rejected their takeoff for wind shear. Second time we came around we got a wind shear warning. I followed the wind shear guidance on the go around. They gave us 3000 ft. When I reached 3000ft we were in moderate turbulence and do to the excessive winds I was unable to maintain altitude. I ended up 200ft high and then shortly after 200ft low. We tried to ask for a block of altitude but due to radio congestion could not. By the time we had a chance to get a hold of NY we were out of the worst of it. We also were dealing with a 1 bleed over pressure and running the QRH. We ended up diverting to KJFK to get fuel since now we had used our extra. ATC said nothing about our altitude deviation.
ERJ-175 crew reported 2 missed approaches due to wind shear followed by a diversion because of low fuel.
