I just recently bought a 2005 f150 reg cab 4x2 with the 4.2 v-6 it has 101,000 on the motor and i am wanting to do a tuneup on it.. I have heard lots of bad things with the sparkplugs breaking, is this a problem i could encounter with my motor or is it a v-8 problem? Is there any pointers someone can throw at me before i start doing this? anything i neeed to worry about or is it straight forward on the v-6's? any input would be appreciated, Thanks in advance!

 

No problems associated with the 4.2.
