Well was playing around a little 4800 rpms was round 8psi 3/4 throttle and let off. The rpms dropped to 400 or so barely running. Sounded like I had a cylinder down. Wideband pegged lean like a cylinder was just pumping air. Limped home thankfully right around the corner. Hopped on the laptop and fired the injectors found 3rd cylinder wasn't firing. Ohmed it out. Toast. What are the chances it fires back up and it didn't lean that cyliner out and shmoked it. Will one cylinder running dry effect the o2 of the other 3 under load? I like to tell myself it happened after i let off. Ha what are the odds of that.
