So I picked up a 97 4.6 t bird yesterday and it seemed to have a small misfire. I figure its just spark plugs. Today I changed them, started up the car and it bogged out. I cleaned the MAF forgot to plug it back in, but it ran much better with it unplugged. As soon as I plugged it back in, the car died. It sounded like a vacuum leak for a second but the noise went away. The car runs much smoother at higher RPM but as the RPM comes down, the whole car shakes. I got out of the car and noticed two wet spots on the ground. Any help is much appreciated as this the first 4.6 in my family.
