yep it sure is finally. i had to replace the intake runner control inside the manifold,(it broke and sent plastic chunks into the valves which kept them from closing and cause the cam to break the retainers and the tappets so the valves just hung open on the rear drivers cylinder). i had to replace two retainers, two mechanical tappets, my mass air meter, my iac valve, my injector plates, injector orings, air filter. all that got blasted from the backfire. luckily i had all those parts at my house from a low mile wrecked ls. the car needs to be retuned though because their tune throws codes.
