Does anyone know why my ford Explorer coughs and splutters for about 2 minutes when starting in the morning?

my ford explorer is very erratic when starting in the mornings.Engine races then revs drop drastically and engine often dies totally.After about 2minutes driving the engine is fine for the rest of the day.Does anyone know why my ford Explorer coughs and splutters for about 2 minutes when starting in the morning?wow....some of the answers....

check idle air control valve. they act stupid only when first started. try holding your foot lightly on the gas pedal. if it stays running nicely then check the iac for sure. i dont know that i am onboard with the cool temp as it would typically cause driveability issues most if not all of the time.

my $ would pull the iac, attempt to clean it with brake cleaner and reinstall. if it still acts up and runs with light pedal pressure then just replace it.

made lots of $$$ at ford on those...not uncommon to replace if the engine has a lot of miles or tons of short trips carboning it up.Does anyone know why my ford Explorer coughs and splutters for about 2 minutes when starting in the morning?
Sounds like too rich mixture in fuel/air ratio if carburetion is applied caused by bad choke adjustmentDoes anyone know why my ford Explorer coughs and splutters for about 2 minutes when starting in the morning?Keep your Ford, don't buy no stinkin rice burner.

I agree that the most likely culprit is the egr valve.

If not, it probably just has a bad cold. Drop 2 aspirins in the radiator.

Does your "Check Engine" light on the dash come on? If It does, your vehicle has set a code which can be retrieved by a repair shop. The code will give you a good idea what may be wrong. It's a lot easier and cheaper to repair if you have a code. Otherwise, you're guessing and may be buying parts for it that it doesn't really need.



When choosing a repair shop, go to one that has an ASE certified mechanic. They're trained in such things. Stay away from any backyard bubbas.Does anyone know why my ford Explorer coughs and splutters for about 2 minutes when starting in the morning?An engine tends to run too lean (not enough fuel) at a cold start. When cars had carburetors, the choke plate had to close at the top of the carburetor to force more fuel into the engine. Modern fuel injection cars have computers that sense the temperature of the radiator engine coolant through the Engine Coolant Temperature (ECT) sensor. So if the ECT is bad and telling the computer that the engine is warm when it's actually cold, not enough fuel will be pulsed through the fuel injectors and the car will stumble until it warms up. Other factors like a buildup of carbon on the backs of the cylinder valves can exacerbate a lean stumble by soaking up even more of the fuel into the carbon on the valves. Try a http://www.BGprod.com service cleaning to clean the injectors, valves, intake manifold and throttle plate. To check or replace your ECT, see the links below. Finally, some cars have an input air temperature sensor element mounted after the air cleaner before the throttle plate that can be easily cleaned.Does anyone know why my ford Explorer coughs and splutters for about 2 minutes when starting in the morning?
your choke is not working properly.
sounds like the same problem i had with my truck, try leaning out the auto choke adjuster on carb and turn it to the front of your motor to lean it out until it runs smooth then adjust your idle to proper setting.Does anyone know why my ford Explorer coughs and splutters for about 2 minutes when starting in the morning?
A malfunctioning cold start sensor, always difficult to find which one is responsible but mark my words it will be one of them.



Experience with similar problems on TOYOTA, Ford, Merc, Vauxhall, they break down over time
Cold start problem , fuel to weak in the morning
I have never seen a ford do well in cold weather. This is a common problem that has neve been corrected.
Fords suck, buy a Toyota
the egr valve is opening prematurely
