Message	When you first start your car it should run rich till it warms up. As the engine warms (and revs fall) the AFR should head toward Stoich. Check your air regulator, AAC valves, and check for vacuum leaks. "If you own a 300zx, you don't have time for a hobby" "If you own more than one 300zx, you don't have time for a life"
