[rpoz-29]

My '02 Z-28 has 7,100 miles. I wanted, (really wanted), to run my club's last autocross today. On the way to the event, I thought I felt a miss, but it went away as fast as it came. During my first run the miss returned, and the light came on. The light went out, and I took my second run. The light stayed on so I left the event. The light will flash for a while, (I counted 10 flashes, 25 flashes, 32 flashes, and too many flashes to count), then stay on for a while. Then it flashes again. It feels like a dead miss. Do I need to take it to a dealer, or can anyone scan it? Have any of you had this issue before?

Sounds kind of familiar to what happened to my Jeep, the code came back as a misfire on #2. I tested the coil, un-plugged injectors, pulled the valve cover, did a compression test.... it turned out to be a bad plug. It became obvious when the misfire jumped to a different cylinder when I moved the plug. It turns out the resistance didn't match another plug, I forget exactly what it was doing wrong, either open or varied according to my voltmeter. The plugs were only 3 weeks old so I was able to return that one!!!
