what the hell is that resistor? I know where it is and I screwed it both ways to hell and it does nothing. ??? could I be ******* something up?

 

It adjusts you idle/fuel mixture. If it didnt do anything, try and get one from the junkyard(free if you got pockets), it might be bad. Look in the FSM though, I did it the way the FSM said to, and it helped out nice w/ my idle.
