Misfiring badly, need help
#11
Sheesh - I had the same experience a few weeks back on the 2003 Disco towing the boat as well. The truck new to me, so was in the process of getting rid of the gremlins anyway. All of a sudden, started mis-firing and SES came on. When I took it in, the code was for the purge valve, so checked all the connections, cleaned the Purge valve, etc. SES went away, but still getting misses.
Anyhow...
Both his misfires are from the same coil pack. Just finished changing my coil pack minutes ago, misfire #1 and #6, (codes P1300, P0301, P0306), which, it's the same coil pack for both of those wires/cylinders...changed coil pack and it corrected the issue. Changed wires while l was in there.

You may need to replace purge valve.

Purge valve replaced with the Hyundai part from the Dealership.... they gave me a discount ($90 down to $75), but still not cheap. Still missing. Heading back in to see if there are any new codes. I do find it interesting I started getting the misfire while pulling the boat... but I am attributing that to a weak spark or bad wire. they were replaced by the PO....
