Subject: Re: 99 ford explorer help!
jeff, has vehicle been scanned? what codes are stored? over-rich mixture can cause roughness until temps begin to rise (remember carburetors with bad pulloffs?). does pcm think it is some exteme temperature (like -200) or is it reading normal? system can also be too lean...causing roughness...but it would probably be very hard to start when engine is cold ....is this of any help?
