I’ve got a misfire across all 4 cylinders and the cel that’s coming up is misfire on random and then a code for each individual cylinder. A weird thing that is also happening is that a relay behind the glove box will click and when it does that everything electrical shuts off in the car, speedometer, tach, radio, everything shuts off but then all comes back on within half a second and it’s happening if I put too much load on the engine and it feels like it’s tripping the electrical system and that’s when it does that flash click and everything shuts off and comes back in a flash. It started out just doing it when the engine was cold and would go away when warmed but now it is doing it at all times.

I replaced all spark plugs last night. I’ve swapped around coil packs. There are two relays I can see in the glove box a blue and a brown one I think they are the PGM 1 & 2 relays I’m not sure. If the relay is clicking that would mean it’s still operational right or no? Should I replace those?

i don’t know which direction I should start looking to next that’s why I appreciate if anyone had any advice

thank you in advance

 

I’m going to start checking grounds, anywhere specific I should check?
