My 6.4 recently started losing power along with gas mileage. Check engine light started flashing and then now it backfires under wide open throttle. Code for Evap issue. Exhaust seems to be running hot haven’t confirmed with temp readings yet. Cat smells a little bad I’ve noticed. 198k on it. About to be swapping the engine out for a wrecked viper acr engine. Plan to rebuild the he 6.4. Just looking to diagnose in the meantime if anyone has her similar issues
