Hello all, I recently purchased a used '97 Silverado Z71 Offroad with ~ 191,000 miles on the odometer. I found this site while searching for a few ideas to help with a miss on cylinder 4. Long story short, cylinder 4 holds no compression so I'm soon to dig into the top end. uch: Not really looking forward to it but it's starting to dawn on me that it's not going to fix itself. Looking forward to reading more on this forum!
