Problem when cold
Not too sure if anyone can help. I have a 1997 323i coupe automatic. When I start her she's fine but. As soon as I put her in gear she idles really bad and tries to cut out. Once temp is at top of blue section she runs fine. I have a new air flow meter so I know it's not that. A friend said it could be the 5th injector - does any one know how I could check this?
