Got towed home yesterday need engine help

The MAX fire does have some circuitry in the cap? Maybe some ghosts there? Have a look at the instructions, maybe there's a way to test the dist.

Might be fuel realted as well... Floats or other.

A faulty tachometer will cause your issue, especially if the needle still moves with the signal wire disconnected.

Don't discount a tachometer as the cause for intermittent spark.

The tachometer needle does bounce around with the engine running even though the signal wire is disconnected. I keep thinking the tachometer is a clue, but without a direct connection to the distributor I don't see why. It is an electronic tach from Speed Hut. The engine still runs rough with the signal wire disconnected.
