Narrative:

Climbing on TECKY2 approximately 4;000 feet given climb unrestricted clearance to FL190 expedite through 7;000 feet. Aircraft given full power to approximately 3;500 feet vsi climb rate. Passing through 4;800 feet clearance cancelled to maintain 5;000 feet. Response to ATC was 'leveling 5;300 feet returning to 5;000 feet.' our return to 5;000 feet was a bit slow and ATC prompted to return to 5;000 feet quickly.TCAS traffic was visible on and to west at 6;000 feet; but no TA or RA. I don't recall exactly due to heavy radio traffic and MCP adjustments; but our course may have been approximately .5 miles west as magenta line randomly shifted during our turn on procedure possibly causing norcal to cancel climb; but we were not notified of that. Norcal then reissued the exact same clearance passing abeam traffic at 6;000 feet. Flight continued uneventfully.
