Again, it's just a WAG - if MAP hose is intact and still suffering from misfire, either a fuel system issue (like fuel pump, clogged fuel filter, etc.) or a vacuum blown under the plenum.
I presume CEL is not on? Can you see if you can jump OBD and pull code?

Yes . My first thought also . ordered a new fuel filter . Will be changing that first and go from there .
I am not sure how to jump OBD to see if there is a code . Sorry .
Thanks for the tip .
