Sun Tach Problem

[Plowman]

A quick way to check the green wire is with a test light and tapping the engine over a time or two. Test light should go on and off[not runing]. Not all coils are good since the car starts,some bad coils run out of spark and give a feeling like running out of gas. Could try another known good coil. The green wire should be on the negative side of the coil witch is also the distributor side. Hope this helps. Paul
