I recently bought a relatively cheap hantek oscilloscope off of amazon so that I can test some of the sensors more precisely, But now I'm curious.
Can a T-pin be backprobed into the coil pack of the spark plug wires and grounded to the frame or spark plug somehow to test for a misfire, or is that not safe considering the voltage coming out of the pack... I havent seen anything about this online, I've just seen ways to check the spark with high end obd scanners.
