Question about 2001 Ford Focus

Ford Focus Sputters

I have a 2001 Ford Focus that when it gets above 75 F or so, it keeps sputtering and shut's down. If I turn the key off for 30 fires right back up(runs normal) and away I go again for about two or three minutes. I changed the spark plugs and wires which only increased the distance I can drive but it did not solve the problem. I also think it might be the coil pack? This problem also occurred about a month ago but by the time I got the car home it ran fine and continued to do so for about a month. What else should I look at? an electrical problem? Also the check engine light is on due to the speed sensor... could that have an affect?

    so i should go ahead and change the speed sensor? basically i was just making the temperature assumption due to the warmer weather this weekend. I'm thinking it might be something in the EMS also due to the fact my AC randomly made my car shut down one day and the hazards also caused the problem once. Should i take my car to a mechanic that can do electrical testing? or just try and replace the sensor first and see what happens?

Your fuel delivery module (FDM), basically just the fuel pump and filter, are under recall. I know this because my 2001 ZX3, and just about every other early Focus have that recall. it's a "silent" recall from Ford, says the NHTSA. This means Ford plays dumb until you say you know about the recall. Ford recall campaign 03N01. It is for a period of 10 years from the date of the original purchase of your vehicle. Mileage DOES NOT matter. There are several recalls still active for the Focus. Go to the Office of Defects Investigation (ODI) website and look up your vehicle.

I also had this problem with my focus when I first got it. Try replacing the adaptor that connects to your coil pack or even that whole wiring mindful -- I replaced the adaptor twice and finally decided to use **** connectors to make good connections from each wire to each terminal. That is probably your best option.

The "speed sensor" is throwing way too much fuel through the injectors and flooding the cylinders, new spark plugs would burn longer, but still die after a while, so that makes sense... but I think the problem might go a bit deeper into the engine management system than that. You say it does this at a specific temperature, so a loose connection somewhere is possible inside the EMS, something that breaks a sensor connection at that temperature, due to expansion and contraction of metal parts. Try looking for evidence of that.

Sputters, lose power, car shuts down

I have the same problem and since I had a similar problem in a grand caravan I changed the same thing I did before which was the fuel pump. Well it did not work and I was about to change the coil and now I see your solution did not work either. Thinking of changing the wires and coil anyway. Could be same symtoms different problems.
