A failed or cracked upper intake manifold can cause vacuum leaks leading to lean fuel trim codes (such as P0171 and P0174), engine hesitation, and stalling. Replacing the upper intake manifold with this direct-fit unit restores proper air/fuel mixture and engine performance. Gaskets are included for a complete installation.
