Question Answered: 

I do alot of stop light switches for this concern,check to see if your brake lights operate.if not check for power into the switch,then press the brake and check for power out of the switch.

Question Answered: 

more than likely your vehicle is a flex fuel model.under the driver's side of the dash is a flex fuel module that is very notorious for this exact concern.it is about 2 inch square black plastic with a small metal bracket that bolts to the center dash frame.

Question Answered: 

It sounds similar to an exhaust restriction.put a vacuum gauge on a vacuum line and rap the throttle while in park.the vacuum should snap back to what it was at idle.if it moves slowly to the reading at idle you have a restriction.also the baro pid is a telltale sign(if you have a scan tool available)anything in the 149hz and below is also an indicator.or if you have access to a backpressure gauge,should not read above 3psi.good luck!
