Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello. There is a TSB for this exact same issue on other ford vehicles with the 3.0 engine calling for replacement of all the spark plugs due to a poor spark plug design from the factory. These plugs can cause damage to the coils or the PCM. The fist step is to replace the spark plugs and ignition coils. Have you replaced any of them?
This is a 2008 model? just clarifying
Ok. The TSB is for slightly older model years, but the symptoms are identical, same engine etc. Personally, I would follow the TSB but I am going to open this up for the opinion of one of the other techs.
Hi Im David, Im going to give you a link to a good video that will help you troubleshoot this issue. It indeed may be the drivers inside the pcm as your years car is susceptible to that.
do you still need assistance?
Is this a 2008 Ford Focus or 2008 Ford Fusion?Just asking because the Ford Focus never came with a 3.0L V6 engine.
The reason being is the 2008 Ford Focus only had a 2.0L 4 cylinder engine.
