I changed the plugs, wires, cap and disc. Also changed the spider injector. And I've changed the thing that rattles when u shake it. Think its the egr valve. Checked all vacuum hoses. Found a few that had holes and changed them. Had fuel pump tested. And changed fuel filter twice since febuary this year.
