i have a crx with a swapped b18a1 in it was running good until the other day it decided it wanted to wiggle a wire loose for the no. 4 cylininder injector. after hunting and finding that problem, somehow the injector went faulty. i replaced the injector, and now it is throwing the code 9, cylinder no.1 position sensor. basically the car runs like crap and im hoping it is because of this. the sensor is good, i checked everything in the wiring, checked the sensor like the book says, but it still is throwing the code. has anyone had this problem, or know why it would do this? could it be because its so off time? any help would be greatly appreciated, thanks.
