as long as its over 100 and the lowest cylinder is no more then 30% less then the highest.
i.e highest is 100 lowest has to be 70 or more.
i would suspect a vaccum leak causing your problem.
to check it spray the vaccum lines with brake cleaner and monitor the idle. if idle changes thers a leak. also spray the gaskets and air intake hose also
