misfire cyl3

hey all 94 mx5 recently i took my mx5 down to hampton downs, where it sprung a coolant leak. managed to limp it home, and decided to do all coolant hoses at once.

to get to some, i had to take off the intake manifold, and i replaced the gasket at the same time.

now i was stupid and put the injectors in wrong and broke a couple, so i got some “new” ones.

i also replaced the ignition coil pack because it got coolant all over it.

now, i have a misfire only on cylinder three. i’ve listened and can hear the injector ticking, but still switched it around with number one injector, but still misfiring on 3. i’ve pulled the lead while running and it’s sparking.

i did check the resistance of the HT lead, and it was around 1k ohms, and according to online spec is 2-5.

i then switched over the leads with 3 and 4 and nothing yet.

i am really confused 😕
