Rep Power: 0

Hey everyone, this morning my 1998 Honda Civic EX coupe started misfiring and the CEL popped up. I used the code scanner and got these four codes, P0108, P0302, P0304, and P0300. It seems they are for cylinder misfires and a MAP sensor. My car got into a small accident a few days ago, no frame damage or anything serious, crushed my headlight and ripped the bumper off, I was able to put everything back and it was driving fine for 3 days. Judging by the timing I feel like this has to do with the accident and not by chance. The only thing that we did to the car was reconnected the turn signal wire since it was cut in half. It did blink very fast on occasion since we did that, not sure if its related but just adding it in case. The car revs nicely in park but in drive it misfires. What would you all recommend I do and check out?

Start with the basics.
check the plugs, check that each plug is getting spark, check that the injectors are firing, check the air intake.
Try swapping spark plugs or injectors to different cylinders and see if the code moves
