Went into town today, about 15 minutes away.
On the way back I got a flashing check engine light with a rough idle. Noticed that if I gave it a lot of gas it would stumble.
Got it home and let it cool. Checked over the injector harness and the wires look OK. Didn't go any further with that.
Pulled the plugs. #1 (one with the codes) had a glob of carbon or something bridging the plug gap. Otherwise it looked good.
#2 and #4 also had some material in the gap but it was splintery and apparently wasn't enough to throw a misfire.
Did a compression test.

I cleaned off the plugs and checked the gap (still .035 on all six).
Going to put it back together shortly. I'm assuming the gunk on #1 plug was causing the misfire codes and they'll likely be gone, but I'm curious what that substance is and where it's coming from.
Also, do my compression numbers indicate anything? She has 176k on the clock and I"m not the original owner.
