Idles okay. Stable when rad fan kicks on. No A/C, power steering. Decent acceleration after 4000rpm all the way to redline of 7200rpm. Slight hesitation of a quick throttle blip. No issues when shifting. Good cruise mileage, gulps gas when aggressive. 5 minute warm up time due to coolant reroute. Driven in mediate warm climate only.
