when the car is running it tends to shake and it seems like it want to shut off. i thought it could be an fuel pump or an fuel filter problem but i dont think thats the issue here. the check engine light is on now,so i had it hooked up so i could get a read out and it said #2 cyclinder is misfiring and my fuel to air mixture is to lean or rich. what is causing this problem ? could it be my TPS sensor or my MAPP sensor or if not that, which sensor should i check or replace ? the motor is an 3800 v6,and i know that the intake manifold can melt due to the heat that the EGR valve stove pipe makes. could this be an early sign of my intake manifold going bad ?
