[QUOTE="alexd607, post: 434608, member: 20234"] [USER=19912]@HDSlowride[/USER] Were you able to figure this out? My 92 YJ is now doing something similar. Instead of 5-10 minutes of running for it to become rough, it's about 30-40 minutes. The thing with mine is I notice it generally happens after hitting idle speed. I'll be driving home from work and I'll make it to the same general area when the roughness starts. If I keep it above roughly 1000 RPM, then it does not stutter/miss/backfire. Accelerating from a stop is when it's the absolute worst. When this first started happening, I would be able to accelerate through it, as the stutter/miss would only be momentary, but it has gotten progressively worse to the point that the jeep will start running so rough it dies at idle once it starts with the roughness. What are the chances of this being a vacuum leak? A buddy of mine suggested that may be the culprit, but neither one of us are very familiar with the YJ's engine. [/QUOTE]
