Review on Dorman 615 177 Intake Manifold by Andy Thorson

Bought this kit to repair my 1999 Ford Windstar SE 3.8L lean burn engine (DTC P0171 & P0174). Before I bought this gasket kit, my engine was idling rough, had poor fuel economy (10mpg city) and sometimes stalled at traffic lights. After replacing the original gaskets, my engine ran quieter, smoother and the error indicator was gone! I'll update my mpg later because it's only been a week. The only reason I didn't give it a 5 out of 5 was that two bolts on the valve cover prevented me from attaching the spark plug wire clamp to it. All in all I would recommend this product to other people in my situation.
