Hello everyone,

Recently I've been experiencing some issues with my 2003 Ford Focus SVT. I live in Wisconsin where it gets pretty cold but it's never actually gotten this bad. Now when I start my car from a cold or even still warm (not hot) start it turns over a lot more than it used too... also when it does manage to fire up, it would usually rev to 2k rpm and slowly drop in this cold weather but it seems like it's not even able to reach that sounding weak. Then this morning I was driving from a cold start and was coming to a stop and my rpms dipped extremely fast, stumbled to keep itself alive and stalled. I'm not sure what is causing this problem. Plug wires, fuel pump? I'm not sure. The fuel filter I just changed so that shouldn't be a problem but it does sound like a fuel delivery problem to me.

Any help would be greatly appreciated!

Long list of "maybe's", I'll start with a question.

Is the idle speed consistent & where it should be the rest of the time?

(IAC not working well could be a cold start problem reflected in it's not revving when cold as normal)

It idles completely normal when it warms up..
