Question:
Why does my car start up rough on cold days?

It's a '92 Dodge Shadow. It never -doesn't- start up. However, during the winter, it typically has a hard time for the first 30 seconds or so. The car sounds like it's skipping a cylinder. Sometimes it won't start at first, and then I have to hold the ignition for 7-8 seconds before it starts up extremely roughly.

Why is this? A compression problem? I think its head gasket is leaking, but I'm not sure because the valve cover gasket is also leaking.

Again, after 30 seconds it runs fine.

Thanks in advance.

Yeah you may have to much of thick oil which is hard to move when its cold. I would get lower viscosity oil so its easier to start. It could be that your head gasket is starting to go bad too. If its loosing compression. I would say it might be the oil. There are NUMEROUS problematic though. I would take it to an auto shop to be sure what it is though.

It sounds like a Sensor problem the injectors are control ed by a multitude of sensors which feed the Computer info,If it starts and smooths out after a couple on minutes I would not worry about it,

PS how are your spark plugs?

check the coolant temp sensor. that tells the computer to put on the "high idle" circuit. it may not be working
