Car was misfiring and sputtering frequently but I wasn't sure what was because I just had a misfire problem about 3 months ago... So I just decided to drop her in the shop, they found out that my intake manifold (which is a ford racing intake manifold) cracked and leaked into cylinder 7. I had purchased this manifold 3 months ago because of a leak in the stock manifolds crossmember! Really disappointed
Doe anyone know if the manufacture has a warranty?
