yes i have checked for vacuum leaks, nothing seems abnormal in that area....
some of my vacuum stuff is bypassed, however with it hooked up, it ran the same regardless.....
the previous owner was a ghetto mechanic, and he tweaked the mixture screw and had lots of other little surprises that i found later on... its possible he friend some part or rendered it inoperable or its jsut malfunctioning causing my issue.....
