4L Newark 1 departure LNAV 90 degree x-w gusts 25 knots windshear advisory. Constant moderate turbulence on climb-out and level off 3000. Aircraft was climbing out of 1200 feet at the end of 4L. Above 2500 foot point flight director and LNAV departure dropped out of legs page/FLT director did not have departure guidance. Constant static on departure freq. level at 3000 encountered TCAS Traffic Advisory (TA) followed Resolution Advisory (RA) guidance. Clear of traffic continued 290 degree heading as per departure SID. Supervisor controller came on frequency with a heading and a climb. Flight continued normally.
Departing Runway 4L on the EWR1. ATIS has LLWS advisories in effect; wind is 32012G20kt; aircraft on final are reporting +/- 10 kts at 300-400 feet. Tower clears a B737 for take off and puts us into position hold Runway 4L. After take off the 737 has a significant left crab and steep climb rate. Tower clears us for take off just as the 737 lifts off; Captain has LNAV selected for the departure and uses max thrust for wind shear precaution; normal Takeoff and rotation. Lift off was approx. mid field; climb rate approx. 2000-2500 + in an attempt to maintain V2+15; but airspeed continued to increase to approx. 180 knots while we climbed through 400 feet MSL. Turbulent climb; approx. 1000-1200 feet MSL over departure end of 4L. Captain called for flaps to one; I move flap handle to position one; a few seconds later I notice the throttles moving toward idle and ALT CAP 3000 feet; climbing through 1500-1700 feet at approx. 185 knots flaps one; nose up angle and airspeed decreasing. I asked Captain if he would like 250 knots and selected 250 in the speed intervene window on the MCP. Tower transferred us over to NY DEP; check in call we could not understand transmissions for all the static - background noise on the frequency. Continued to concentrate on airspeed; flap retraction and level off at 3000 feet. Departure asks us if we are on the departure? I respond affirmative. Captains Flight Director was centered; but I did not notice that LNAV had not turned us to 060 heading that was in the FMC RTE. We then noticed departing 737 ahead of us turning left to 290 heading in front of us; climbing through our altitude; followed by an RA. We complied with the RA; flying below and behind the 737. A different NY departure controller then turned and climbed us to the southwest; then east to our en-route course; transferring us to NY center. We continued our flight without further incident.
B767 flight crew departing EWR in strong gusty crosswinds; reports the flight director not following the programed EWR1 departure resulting in a TCAS RA. Momentary lost communication on the departure frequency due to loud static and turbulence were factors in the incident.
