help ... poor cold start
I have a 2005 Outback with the 5.7 EFI. When the motor is cold, it will not adjust for the cold engine temp and will not stay running when I start it. I have to put it into neutral and warm it up like a carburated engine. After it is warmed up, it starts fine the rest of the day. I do not have a dealer within 10 hours that can put a scanner on it to diagnose the problem and I have already put in a new temp sender and an IAC motor. Has anyone else had this problem ?
thanks
Marlon

temp sender
I replaced the one with the 2 wire (black & yellow). They are quite inexpensive, so I guess I might as well change the other one too. Thanks for the reply, I was not aware that there were 2.

I don't think changing the one for the gauge is going to help with your starting problems.

Have somone turn the ignition switch on then off again after a couple of seconds. You should feel the pintle move (expand and contract) If it doesn't the IAC might not be getting powered properly.Larry Engelbert

cold start
After I posted that last message about changing the guage temp sender, I felt like a bit of a dork when I read it. It has been this way since new (now have 52 hours on it. I'll try to test the iac motor like you said.
Thanks for the input
