2003 Mitsubishi Eclipse 6 cyl Front Wheel Drive Automatic 100600 miles
I recently had a tune-up on my '03 GT Eclipse. It is a v6 and in order to change the plugs and wires the intake manifold was romoved.A new gasket was put on before replacing the manifold. At the same time I removed the resonator from the exhaust to get a deeper sound. Now when I hit 3000 rpm at idle or while driving and getting on it it whistles. Is it the lack of the resonator or a leak in the intake manifold?
