Alright i was on here before and you guys helped me out a lot well now i have another problem with my 2003 dak when it is in either park or neutral it likes to have a knocking problem im stuck at what it could be and i also have a problem with my oil pressure it like to go up sometime and other times it dosent all depends on its mood now i think it might be the oil pump any buddy got any other suggestions on the oil pressure problem or the knocking prob

 

if its a 3.9 or 5.9 check your plenum gasket. look down into the throttle body with a flashlight and see if you see any pools of oil in the intake manifold. also, try changing to a colder spark plug. autolite 3923's gapped at .040 work pretty good.

 

it a 3.9 thanks all give that a try
