    This is a 6.0 Powerstroke Diesel it continues to run poorly even after it warms up It makes a lot of noise. I have several 7.3 diesel F350 all approaching 500,000 miles without any major work not even fuel injectors replaced and they are 1995's and 1997's . The 2005 6.0 has only 200,000 miles and has already cost a fortune in repairs. Which have not solved the problem. Once again the problem is Hard Starting when cold no power and makes a ton of noise. When warm runs rough and pulsates, can run on highway and get up to speed of 70 mph + but uses a lot of fuel and still pulsates at these speeds.

Change the plugs, wires, distributor cap and rotor - air filter and fuel filter. Also, once it's started and at operating temp - pull the vacuum line off the distributor (if equipped) and put a timing light on it. If it needs timed, do so with the vacuum line off - once it's set to where it should be, re-connect the vacuum line and adjust idle as needed.

After this, fill up the tank, (one of if two) and poor 3/4 can of SeaFoam in the tank. Pull any and all vacuum lines and insert them into the can - (hold idle up with hand or have someone help to prevent truck from dying). Run through the entire tank, and refill with desired grade fuel you usually use.

Also, make sure you have no exhaust leaks at the manifold, intake, catalytic converter, or muffler.

The catalytic converter may need to be checked as well, as if it's plugged it will suppress the engine exhaust.

Please let me know if you need any further assistance.

You may have low fuel pressure which the engine isnt dealing with while cold. The engine uses base setting during warm up and then switches to active sensors once warmup is achieved.

You should also make sure you have spark at all cylinders. Sometimes a plug gets chewed up by detonation and ends up being way out of time!

How many miles on the engine?

    Ah...a diesel! I do feel silly.



    No power and sounds like marbles in a coffee can. With a diesel all you have is injection timing. A mechanic would detune the motor to hear timing knock versus normal ignition sounds.



    On the cheap side how about changing the fuel filter? it might give you better fuel pressure if that is what is affecting cold running.



    Keep us posted!

    These fellow owners of powerstroke diesels mention getting your engines control module reflashed.



    I guess Ford has some updates that might make cold starting better.



    Also checking your engines computer for codes might help narrow things down. This could be nothing more than a couple of plugged/bad/weak injectors.



    Sorry about the mixup earlier. I didn't see anything on your post about the truck being a diesel.

    It just said 6.0 Ford F350.

    I especially liked the check for coolant leakage into your EGR valve.

My 1988 dodge d150 runs rough when cold and going uphills


how old is this truck ? needs complete tuneup, new air & fuel filters, wintertime brings out the all the problems, also, replace EGR valve, & PCV valve, they will choke the hell out of the engine, your filters are very important also, if there dirty/old, they will starve the engine. talk to the ole girl while you do all this work, she'll respond, I promise !!!! make sure all the vacumn lines are good, tighten all throttle body bolts, etc

Hard starting, rough idle when cold, then smooth running when warm


Need year/make/model/mileage of vehicle to provide a more specific set of troubleshooting steps.

When was the last tune up? Hard starts when cold are usually caused by fouled spark plugs, worn plug wires, or weak ignition coils. Fuel systems are not as effected by temperature changes as the ignition components.

91 Explorer 6cyl XLT standard is super hard to start, the engine sounds muffled when starting and while running, quickly overheated once it was running, looses power when pressing accelerator.


Could be a clogged catalytic converter. It could also be a bad head gasket allowing some coolant to enter the cylinders. Check for milky grey oil.

Sounds like possibly more than on problem, crankshaft position sensor, or ignition module likely on starting prob which maybe affecting shifting due to hard code in ecm, or shift prob could be shift solenoid in valve body of transmission. Both parts readily available from local parts store

Difficulty starting when warm, OK when cold


Have you checked the fuel pressure regulator for leaks into the intake

Now starting when cold, it belches black smoke and runs very roug


Sounds like either the float level is too high, there is a problem with the float needle valve or the power valve is stuck. I'd take the carb off and either replace it or take it apart and check everything inside. If you do nothing, chances are it will either get worse or if it's a small piece of junk inside, it may clear up by itself...I'd take it apart. Since it's pretty new, if you are careful, likely you won't need a gasket kit.
