the 98s had a few of the following problems...
ls1 intake with egr
faulty hatch releases
Perimeter valve cover bolts
coils were mounted individually and not on 1 bracket, have to remove one at a time.
paper water pump gaskets liked to leak
exhaust manifolds were more restrictive
head castings were different and werent as good as the later ones
15 gallon steel gas tanks
98 blocks have smaller cylinder sleeves and cant be remanned
early pcv system that was crap
no idle adjustment on the throttle body
not to mention little electrical gremlins that pop up in all fbodies but show themselves more in the 98s....such as window motors and leaky heads/tails/corner lamps
