Do cars run rough in cold weather?
Most newer cars and modern vehicles have a throttle that is designed to regulate engine speed and airflow through the system. If too much air gets mixed in with the fuel, then this can cause the engine to misfire, resulting in a rough idle when cold, usually at a higher RPM.

Is the Ford Expedition running at full throttle?
Once started the car runs fine. I gave the car full throttle and didn’t experience any hesitation, bogs, so it seems the fuel pump is capable of delivering and the fuel filter isn’t clogged. As far as spark, the car runs fine. I read something about an idle air controller that lets air in with the throttle closed.
How long does it take a Ford Expedition to start?
My 2003 Ford Expedition takes a longer and longer time to start. When it was new it would start on the first crank. Now it takes about 3 seconds (seems like forever) and a little bit longer when it’s cold. I took it to the ford dealer and for a $90 diagnosis they couldn’t find anything wrong.
Why does my Ford Expedition have a leak?
Inspection showed a plastic hose rubbing against a metal spring with a small hole in the plastic hose, causing a leak with reduced pressure. The replacement assembly came with a plastic sheath around the metal spring, so it seems Ford was aware of the design problem and fixed it.
Can a Ford Expedition idle in cold weather?
This has been happening for years, only when below 28 degrees and only on idle at a stop light. Engine RPM’s drop then rev back up until I accelerate. Once weather warms up it stopped. This winter, which was really brutal for Salt Lake, it started before the cold season and finally got a “check engine light’.
