I recently got a 98 gt 4.6 automatic it has had some mods done to it and im needing help with few things..P.O. put a block off on the egr and the check engine light came up with that so I took the block off and the light came back on with same thing? Would u think it needs a egr positioner or egr valve?
Also its lowered and it sometimes creeks...in the front and he p ut all new stuff in the front...he said it does that after a rain a rubber boot or something hittin the spring i have no clue? Would really like to raise it too stock but I dont know how and how hard it would be any help on that let me know..and last but not least
He put 3.73 gears in it and my speedomter is 15miles off when Im doin 70 its really doin 55... What do i need to buy to fix that?
