    Looking for some help here. Vehicle started miss out of the blue. rough idle shuts off and even miss`s threw acceleration. I replaced the intake manifold gasket, MAP & MAF sensor, Plugs wires and still didnt fix the problem! :grrrrrr:

    fuel pressure at rail is 60ilbs. Im clueless on what else could be. Gunna try new coils tomorrow but idk. gunna hope for the best i guess. anyone else run into this problem. my truck has 204,815 miles on it.

    A P0101 is a mis-fire on the number one (front driver's side) cylinder. It is probably the coil for that cylinder.

    Shady, sorry I'm leading you astray, I just realized I gave you the wrong info, my tired brain thought you typed P0301.

    P0101 is a Mass Air Flow problem.
