where is the pmd location? is it kinda like fish biting type of skip?

 

Fish biting - (or fishbiting) This is the description for when the engine may "miss" or may not fire properly for a very brief instant. As always, do not rule out fuel supply issues with lift pump, OPS, and take a look at PMD. Remember to do as much diagnostic work to prove out all parts that are at fault.
