I am new to the Ford Truck world. I purchased a used 07 Screw on July 1st with only 12,000 miles on the clock. I have found that after starting the motor (COLD) it takes a few seconds before the engine will run smoothly. If I start the engine and then place the trans into DRIVE, the engine tends to sputter for a short while and then smooths out. The sputter shows up as reduced power and a obvious roughness. Once the engines warms up ( or a sensor warm up ) all is fine. Again, we are talking about 5-10 seconds to warm up.

I have owned a number of vehicles and this is the only one I have ever had that needs a bit of time at start-up to run well.

Now, I don't need anyone to say, "let it warm up first" but am looking for what might be the cause. A weak/marginal sensor? Is this a normal symptom for a 5.4 3V?

Anyone have any ideas.

Thanks! By the way, I love my truck......

 

at least wait for it to idle down before you put it in gear. most vehicles do that when they are cold.

 

What did you drive previously?

Let me be the first to say "let it warm up first".

Do your engine a favour.

As far as I know no motor will like being started and driven with no warm up time when it is stone cold. Are you way too busy to let the oil circulate for a minute or two?
