94 325i fouls plugs in 2 miles and runs rough when it warms up. So I put new plugs in. Drove about 2 miles it started missing. Pulled the plugs and thy where fouled. I start thinking somethings up. cleaned up the plugs put them back in 20 mints after pulling it in the garage so it was still hot. fired it up and it was missing with good plugs. so i waited till the mourning started it up ran perfect. About 2 miles down starts missing and fould the plugs. So my guess is that something is going treabley wrong when it reches normal run tempter. But what? If you know the spark plug gap let me know.
