My car is throwing a P0174 code at me. I've gone the usual route and checked for exhaust leaks on both sides and I can't hear one or find one. I have replaced a broken EGR stud and gasket and retorqued the bolts. I don't have a vacuum leak on the intake anywhere I can find. I am pretty sure that both the EGR and MAF are good. How often does an intake manifold gasket go in these V6's? Could it be a bad O2 sensor? Poorly sealed dip stick? What are the common problems that others have run into while owning their V6's? Any help would be greatly appreciated. Cheers.
