The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.

Really great car and super fast when you have the need for speed. I even beat benz's and bmw's on the straight-aways.
Great Car picked mine up with 30,000 miles on it. Have only had minor issues as wiring, Lights, Battery, Wheel Bearings. Would recommend this car to anyone that loves a fast smooth ride that 3.8 motor is great. If you have the GTP I would recommend PFYC.com they have great parts for upgrading your ride.
