Hello, i have a problem with my focus, when the engine is cold (left for > 5 hours) it has trouble starting and also stutters when put pedal down until the engine warms up (like 25 miles of driving) this is driving me mad as its quite dangerous at busy junctions when i need to get off quickly and it stutters. any solutions, its not the battery as i have just changed that and it did help a bit but the problem persists

Does the car have a lot of miles on it? It could be a plugged up injector or even a couple of them, or it could need a tune-up. In the mean time, let the car warm up before you take off. Let it idle for a couple minutes, five should be more than enough. That'll even give you time to get the car warm inside too, not to mention pick what CD or MP3 you want. Just remember to give it that extra amount of time. To quicken up the warm-up process, hold the throttle down to keep the motor at about 2k RPM, and when the needle on the temp gauge moves up slightly, the car should be warmed enough to drive.

If it's not warmed up until you have driven it 25 miles, I'd suspect a problem with the thermostat. If if runs poorly and is hard to start when cold, a problem with the cold start (or automatic choke) system. Sounds like you need to get it in to your mechanic and have some maintenace done on a couple of systems. Good luck with it.

Temp sensor that sends the signal to the ECM might be bad so the ECM dosn't know the engine is cold and is not adjusting the air fuel ratio for a cold engine.

when problems like these start happening it is quicker and cheaper getting a diagnostic check before wasting money trying to eliminate each suggestion someone gives you, a test will take you straight to the problem. Best of luck.

once you ran it dry you in addition to could sucked all the airborne dirt and dust that replaced into in the tank into the device. attempt changing the gas clear out and getting some injector cleanser. If that doesn't clean up the priority you ought to could desire to drop the tank and examine the clear out in the tank and the gas pump.

Go with wally on this, otherwise you'll be replacing/fiddling with parts forever possibly with no cure. Get it done pdq, as you say it's dangerous if it hesitates as you pull away

Plugs,wires,cap. However I found that with all 4 cylinders,I always warm them to operating temperature before driving when it is cold.

could be the thermastat,for starting in cold weather it could be the engine oil,old oil gets thicker with age and thicker still when cold,if you change it get a winter grade.

The easy possible fix:
Could be water in the fuel. Try that STP gas additive that eliminates water from your fuel system.
The more involved possible fix:
Check your fuel pump, filter, and lines.
