when i first start it (cold) very sluggish and pops back in the trottle body, if i floor it then it cuts off. check engine light comes on,ran a scan on it and came up running lean bank 1 so i replaced the o2 sensor , fuel filter, reset the computer,and it still pops back through the trottle body when its cold. when it warms up it doesnt pop back
but it is still sluggish.... ANYONE GOT ANY IDEAS THNAKS!
