Can some one tell me what this csrew looks like and the location. I can get a striaght answer on another forum.

I need details or a good picture.

 

isn't it right on top of the intake manifold... It should be covered by a piece of rubber right next to the 13b fuel injected sign on top of your engine for the 13b.

 

Is this the N/A that is described here ???

Is it on the BAC valve on the turbo modle ????

Whats the procedure for adjusting idle/rich screw ???

Thanks in advance

 

That adjustment is S4 only, there is none on S5 cars.

 

If you are talking about the one Mazda has purposely buried underneath a half an inch of rubber sealer its supposedly somewhere over near the front of the engine bay where the air intake box is but I havent been able to find it myself and its hidden because they didnt want people to ever really mess with it. The other one is right on top of the dynamic chamber/throttle body area under a black plastic cap but dont be suprised if the caps gone and its just the screw. Jumper the leading and trailing green plugs at the coil packs and adjust the screw i think right is rich and left is lean makes sense right. I am talking about a N/A 13b. Any series S4 OR S5
