Rough Idle When Started
When I start my 92 F150 302 V8 in the morning, the first thing it does is drop down below normal idle rpms and it acts like it is going to die. This lasts for about 10 seconds, then the rpms come back up and it is fine. Can anyone tell me what could be causing this? Thanks

Pull any codes you may have. I'd try the Idle Air Control Valve. First cleaning it and then replacing it if mandated. The temp sensor may be contributing also. Check the codes by going to fordfuelinjection.com and learning how to for free, no reader necessary.
