my 91 3.0 has a chatter under the hood (sounds similar to a waterpump chattering kinda). narrowed it down to the distributor and cant figure it out. it goes away as the truck warms up and is really loud when its cold out.
thought it could be rotor rubbing on the cap. put in new cap and rotor, still does it. the new cap and rotor does not rub.
Any ideas??!! thank you!
