this past weekend i did a mpfi swap for a friend (and befor that my car went into limp mode throwing code 4) i went over every thing i did or so i thought, changed dizzys, ecus, and checked the wiering so i thought. well i over looked that when u do a mpfi swap that u change the crank angle sensor to put in the cylinder position sensor. so ur crank sensor is in pins b10(orange wire) and b12(white wire) and ur cylinder position sensor is at c1(blue/green wire) and c2(blue/yellow) havent entierly checked on my car cause im wating for my engine to go in but i hope this can help some one out. also if any one has something to add to help put in on here
