hi, i have an 1987 bmw 325is(E30) and i recently put a cold air intake on it, ever since it has been acting very weird. On left turns it will cut completely off, hard and light turns. Some times it will cut off when im idling at a light or sign, and won't start for a couple minutes. I've tried putting the old filter back on, that didn't help. Someone please help me out.Hank
