Hi guys, i have a 1989 328 gts, it has a cold running issue. It starts up first time, but then runs like a bag of nails. the minute you take the rpm past 3000 rpm it runs fine. When it reaches operating temperature its perfect. I had it on a gas bench, when it is cold the co% is 0.1 to 0.2, when it is hot it is 1.75 everything seems to lead to the warm up regulator ? does anyone have any ideas thanks guys from the UK
