  • BP motor surging

    hey guys, i've got an issue. My festy will start up and idle correctly, but when i try to accelerate it falls on its face, if I lightly touch the pedal the motor will surge really bad, as in itll surge to 3.5-4k rpms then bog to 100 or almost die. The fuel pump is hardwired and kicking, I'm not noticing any vacuum leaks but that's what im thinking it is. the O2 sensor was loose but i tightned that up and had no changes. any thoughts?

      Well I'm going to take it in. the MAF wasnt level so i repositioned it more level, battery was dead so i tried jumping it, tried starting it and saw sparks coming off the positive lead into the engine bay and when i pulled the maf off a little bit of white smoke rolled out of the tubing. I'm going to see if someone can take a look at it, hopefully they will accept it, and be able to figure it out. Thanks for the info, but I'm afraid im going to burn through another harness

        Sounds like a timing issue. Are the plugs wires correct. Also make sure you have good grounds.
