Hi! Have you replaced the automatic transmission fluid lately? If the fluid is burnt issues like this occurs. Please try replacing the fluid first and see how it goes. Hope this helps and have a good one!

The best idea is to scan the Engine Control Module (ECM) memory for stocked faults (Diagnostic Trouble Codes - DTC), using a diagnostic equipment connected to the data link connector of the car. Then you will be full informed about damaged components (e.g. ignition coils, injectors, various engine sensors, oxygen sensors, ...). Then the ECM memory can be accessed and erased by errors (ECM reset), after bad pieces replacement.

08 ford focus TDI driving sluggish, esp light came on, car went limp and then cut out....sat for a few minutes restarted and drive perfectly....happening often


How many miles on it? Coil-over-plugs and spark plugs may need changed. They can throw electrical interference which can put you in Fail-Safe mode. Happened to me.
If car has over 70K, change the Coil-over plugs and spark plugs. Don't forget to change a fuel filter every 30K also.

Check the front engine mount..If its bad it could make a noise while turning or reverse..Hold the car in gear with your foot on the brake and carefully raise the engine ..do it in both reverse or forward and look for excessive movement..

2001 Ford Focus stopped running while i was driving and wont start. Makes a churning sound but no power is going to engine. I changed the ignition coil, still wont turn on. Any suggestions?


Can you explain more so I can help. What do you mean still wont turn on, engines doesn't start or starter motor doesn't turn. Have u taken out a spark plug and connected it to the cable put the end of the spark plug to a ground and make someone turn on the engine for a few seconds you should see some blue sparks. Carefully use gloves. If no sparks, spark plug is bad next thing to check instead of putting the spark plug in the cable put Philips screwdirver put the screwdriver near a ground not touching about one inch make someone turn the engine for a couple of second you should see the spark jumping from the screwdriver to the ground, If there are no sparks ignition coil or spark plug cables are not good. But u say u changed ignition coil so maybe your cables are not good. There is a connector near the ignition coil disconnect it and turn ignition switch on measure the voltage you should have in between 12vdc + or - .5 vdc if no voltage present there is a blown fuse, Check for it

Try the fuel filter. If you have had the plugs, wires changed it may be the fuel filter.

Engine turns but won't start


What year is the focus, And have you checked the ford recalls on the car? I know that when I owned my focus there was a recall with the fuel pump in the tank and i had somewhat of the same problem myself. If your only getting gas to only ONE spark plug, your issue probably lies somewhere in your fuel delivery system (i.e. Fuel pump, fuel filter etc. etc.). Which would also describe the " It stalls out then the engine won't start for along time again.". Let me know, I'll keep trying to troubleshoot with you. Good luck!

Severe hesitation, bucking


Sounds like the cat may be blocked. Stand at the tail pipe and get someone to rev it. If you get a whooshing sound from the exhaust, investigate further up the pipe.
