Replaced blown head car hesitates on 2002 Mazda Protege

Had my mazda head gasket changed on dec 3 , it hesitates when you take off...check engine light sometimes comes on then goes off....most of the time it doesnt come on..head gasket under warranty just seeing if after a month is there something that has to be adjusted since most of the enginewas taken out then put back together....thanks for any advice

intake gasket slipped ,cracked ,or or intake manifold is not aligned right or not torqued to specs. other possibility to much sealant in one area if used. and yes all bolts should be retorqued but if this happend right after repair it will be the intake area as discribed above

does that mean has to take the head gasket back out and replace? OR do u think re torqued will fix the intake gasket like the head gasket?
