Stubborn Cylinder 1 Misfire
 

I am chasing a cylinder misfire that won’t go away. It all started when I washed down my engine (retard moment) I replace the spark plug and replace the coil pack like 4 times the last replacement being the oem coil pack. Every time I replace my coil pack the car runs fine for 100 miles then back at it again. I don’t think it’s the injector because the car runs fine for a while then starts misfiring. Any input would be appreciated.
