1988 mercury

[somedatnew]

When in idol right three cylinders fire. Sometimes the left three fire. The motor idols well for a wile than later not so well. When under under way runs great. My bigest question should it only run on three at idol. If so could i have the idol set to high making the outhers kick in spoty. This is something simple what am i missing.Thanks

It should idle on all cyl.

Need to know what model and serial. Some models drop on side as a shift interupt and can cause a problem.

Or a broken trigger wire, switchbox. Knowing what madel helps determine where to begin.
