Ran it for an hour, sat for 20 minutes, rough idle after start
Just as the subject says, took the 94 out for about an hour in 70° temps today. Sat about 20 minutes before I started it up again, and it would barely stay running for a couple of minutes until it smoothed out - had to feather the accelerator.
This hasn't happened before, any ideas?
Thanks!

Too many things could have done that. I am sure you will have to wait till its doing it all the time before you can truly know what caused it.
Mine did it once. I just drove from work to the doctors office, about 50 miles. After I finished my appointment, I started the car and it started great then within about 5-10 seconds the idle got kinda rough but only lasted about 10-15 seconds. It cleared out right away and hasn't happened again since. That was about 500 miles and 30 starts ago.

Start with your coolant sensor.
The fact that your cars runs rough, you need to feather it until warm tells me that your coolant sensor is giving bad information to your ECM.

I've put about 1k miles on it since purchasing in November - 29k on the clock.
This is the first time it has reacted this way, and it was fine the two or three times I have started it since.
