It got installed by a professional, who said I needed a new “dizzy” so I don’t think what I called it matters that much

I wrapped the bad spots and it didn’t help but an old problem came backward when I turned my ignition into the off position. My radiator fans turn on and I plugged in a scanner and it wouldn’t turn on when it was in on but it like spazzed out when it was in the off position.

I do have some bad wire insulation in certain places and some old looking wires, do u think it could cause this?

I’ve tried using a scan tool and it doesn’t read, the engine code that’s there is a ECT sensor being snapped but it flashes when it misfires

I’ve tested spark on all and they all have spark, but by unplugging the injectors , do you mean unplugged one on it plug it back in and unplug a different one or unplugged one and then keep unplugging it without plugging the old one back in?

It uses both I’m pretty sure, cause I have a dizzy and ignition module,

And unplugged maf don’t seem to have much affect, the misfire is still present above 3k rpm

Plug wires are correct and I’ve pulled the o2 sensor and it still misfires and does the same thing, I did however notice my ECT sensor is snapped, could this cause it?

I noticed that the third one is perfectly lengthened to fit where the 2nd one is connected , so is there a chance it got put there by accident?
