Weak idle right after startup.
I have a 2000 Ranger with the 3.0. In the morning after I first start it up, it has kind of a low weak idle and takes a few seconds to idle up to normal. Any ideas what could cause this? Any help is appreciated.

Acting out IAC probably belongs on your suspect list, as its responsible for maintaining idle speed. So, maybe remove & clean it internally with a plastic safe product, like CRC QD, or MAF spray cleaner & see how it goes. Cleaning may not last, it didn't for me but was a good trouble shooting step & probably why Ford recommends replacement when it acts out.
Do you have a CEL lit???? If so, most autoparts stores will scan the computer for trouble codes at no cost, then post All code Numbers as they can offer up good trouble shooting clues.
