Hello all, on the passenger side, between the suspension tower and the air box, there is a little black *** with 2 screws on each side of it that has arrows that say L and R. (it also has a little black box right on top of it) I like to play with things, and such and it looks like it wants to be turned left or right :0) What is it? thanks.

 

that's the fuel pump resistor.

 

sounds like the mixture adjustment screw to me

 

ok, so mine is either broken or ... something is wrong with it. It has like hard crusty slime on it. Im looking for my camera cable so I Can show you the pictures, but it doesnt look like there is anything I can turn left or right. Am I missing something?

 

if it was taking to a Mazda certified repair shop, the techs used to fill the hole with a epoxy/silicone/don't screw with factory settings goop.

 

hmm thats ... no funnnnn... ok I will just wait till I can get my cameras cable. ( I think I left it in seattle) But yeah looks like it was filled with something like that, I can chick away at it pretty easy..... I cant tell if its a screw in there or if its just a like metal connection .... *depression*

 

It's no mystery. It's the Variable Resistor and is described in the online, free FSM. Fuel section. It only effects IDLE nothing else. It's a mixture screw and has STOPS at each end that you don't want to force past. You can figure what the R and L stand for.

 

Mine doesn't have L & R. Which direction is Lean?

It really doesn't matter.
The official adjustment procedure is to keep turning it until "idle is highest / best".
Only those that have to pass emissions might be interested which way is which...

Actually, passing emissions IS my goal.
