Hello all,

I have a 1993 945T 91K miles. The car runs fine when warm, but during the first minute or so, it runs pretty rough. Hesitates and feels like it is running on 3 cylinders. I just cleaned the throttle body and idle control valve (neither were that dirty). I have also replaced most of the vacuum lines and the air filter. It has new plugs and the wires look good, but I can't tell if they are original.

It has been getting worse during the last month. Don't know if this correlates with the weather getting colder, or if that is a coincidence. Temp is still above 45F outside here. If the car is warm, this does not happen on start-up.

Thanks for your help,
Steve
