(IMG:style_emoticons/default/headbang.gif) Ok, I need some help. Patient:'74 2.0 Djet with Pertronix. Symptoms: Tach dancing intermittently; occasional skip in the motor, sometimes worse than others. Today the car drove alright with an occasional miss and the more occasional dancing tach, but tonight, I could barely accelerate beyond about 2500 without it skipping and missing. The tach dances are not always accompanied by a skip. I just changed the cap and rotor, but that does not seem to have helped any.
Where to look next? I would think the dancing tach might be a good clue..... Plug wires, plugs, pertronix, coil are all new within the last 18 months...... |

You might want to try disconnecting the tach feeder wire at the coil (black/purple stripe) and see if the problem goes away. It goes from the tach to the relay board and then from the relay board to the tach so there is a possibility of four connectors that can cause problems. If either of the connectors at the relay board plugs are loose or have gotten corroded the missing/intermittant tach can result. I ran a new wire on the race car 914 to bypass the connectors so there will never be a problem with the tach feed. Good luck
