So I've got the Toyota 20r with an HEI ignition module running off the magnetic pickup in the stock distributor. The HEI ignition module I'm using is a Pertronix Flame Thrower III with a Pertronix Flame Thrower III coil as well. I've previously posted about this engine so it might be familiar to you. Stock Toyota Ignitior modules are very expensive is why I went with this setup.
It's got new plugs, wires, cap, and rotor. Total ignition timing at 800 rpm is about 10 degrees.
What's happening is that every few seconds the engine has a misfire or two. It happens at idle and when the engines revved to 1500-2000 rpm. It seems to be an ignition problem since, with the timing light on, the timing light doesn't flash when the engine misfires.
I've checked all of the connections to the coil, and the ignition module. The air gap for the distributor pickup coil is between 0.006 and 0.008. I'm wondering what could be the cause of my misfire. I'm going to pick up a cheap coil at Autozone tomorrow to see if it's the coil. Any thoughts or suggestions as to what could be the cause?
