i recently had my b18a1 rebuilt at a machine shop,i put the motor back in and fired her up. its only running on 2 cylinders ,all 4 are getting spark&fuel.it will run on any 2[not 2 paticular(?) ones]anyone have a clue?

if i pull the wire off of any 2 plugs,the other 2 remaining will fire,wires spark strong,pulled new plugs soaked w/ fuel,plugs spark

problems were due to fauty map sensor [3 bar GM]reburned chip for stock,runin 11psi until new 3 bar , process of elimanation works every time!
