So I don't daily drive my R/T and since there's no shows going and hadn't all summer I haven't driven it on any extended trips. I do drive it once or twice a week a good bit after it gets up to operating temperature. Probably a good 10-15 mile total trip. It was a little cooler this evening than it has been for awhile and I've noticed even a few previous times the idle will drop a bit when you stop at a stop sign or light. It's only briefly and it quickly recovers so if you're not paying attention you may miss it but I felt more this evening. No Check Engine, I was a tick before the redline on empty. It seemed to clear up more as it warmed up. It's usually until you drive it for a few miles. What's that a sign of? It's properly tuned, no codes, all stock except for the Superchips Flashpaq 87 Octane Tune.
