I have 2002 honda crv 2.4 L 4-cylinder with 158000 miles. I never had a problem till one day the check engine light came on. I scanned it and it was a p0300. I looked at the spark plugs and boy they were fouled. I bought new ones, then 3 weeks later, same engine code. I take a look at the spark plugs and they are fouled again. 3 weeks! The coils are all in good condition and they work properly. I took a screwdriver (Safely) and checked if the coils made a current. The spark plugs were dark/brownish in color and I have no idea what can be causing this. I deleted the code recently and it came back already. Is there a way to check what can cause them to foul so rapidly?
you need to find out what's fouling the plugs.
It's either running rich (try cleaning the MAF and injectors), or it's burning oil (try compression test)
Did you try out Joe’s advice?

Also, I noticed it only misfires on a cold start and just recently the check engine light started to flash and the engine sounded horrible like it was struggling to turn on. The light then just stopped flashing and stayed on after a few seconds and the engine went back to normal.
