I can hear the injector clicking away just like the others so I'm thinking it's working, I pulled the plug and it looks normal, but it's a Bosch plug and looks old so I do plan on replacing them all, it is getting spark (hooked it up to a lawnmower engine and pulled the cord with the plug outside the engine)
Gonna try coil packs but I'm thinking it's a vacuum leak since the problem goes away and smoothens out at any rpm above warm idle
