My 1998 740 IL runs great at cool temps, but once it reaches normal operating temps its seems to develop a slight miss. It doesnt do this until it reaches temps. I have heard everything from plugs, wires, to coil packs. Can you help? Thanks, Jerel

Check fuel delivery, fuel pumps can do some weird things, like pump bubbles of air and trick you into thinking its fuel.
