Ok, Im having some wierd trouble out of my MJ. It takes it forever to start, it trys to start but to no avail. When it does start it runs perfect, and doesnt have any problems whatsoever. I have good fuel pressure, good spark, and air. But now when I unplugged my MAP sensor it tried to fire, and it fired up. I had to feather the gas pedal to keep it running, but it ran. So Im kinda wonderin if my MAP sensor is bad, or is thier something I havent though of.
