Default Cold start help

When I start my car in the morning, the car runs pretty rough. I have a hard time driving and keeping it going. Once it warms up it runs great. I checked the ECT with an ohm meter and it appears to be operating normal. I measured 41k ohms when it was about 60 outside. I have cleaned my IAC but I wonder if it needs it again.

Any other ideas?

I just checked the IAC solenoid and it measured to be 0.3 ohms. Does that sound right? The site I found says if it isn't anywhere from 7-13 to replace it. Could that be my problem?

Turns out I measured the IAC wrong, it was 9.4 but I went ahead and replaced it anyway. I guess I will see how it runs here in a bit.

I just found a bunch of vac leaks. I guess this is probably some of my problems. I am running new lines and will go from there. I have been getting an EGR code for a while now and finally decided to take it off and clean it. The valve was frozen and wouldn't move. It does now so now I will see what happens once I get it all back together. I am going to work on it some more tonight. Wish me luck!

It is kinda sad, thanks for pointing that out .

I haven't tried that one yet, where's it at? I am actually enjoying San Angelo, its nice and small but big at the same time. I don't have to deal with any traffic, I can get anywhere in the city within 10 mins. I love it!
