misfire po300
About a week ago I got a po305 code. Today I got a po300. I am thinking coil pack going bad. Am I on the right path? Since my header install its been a ride with all kinds of codes.
1997 F250 LD 4.6 auto 4x4 supercab.
In last week. Po305 code. Replaced plug, tested wire. Cleaned EGR ports and replaced the valve. Got the p1100 code. While checking things out on that code I got the po300.
the truck has 80k on it now.
During the header install I replaced all o2 sensors.
