Ok... It's not a solenoid, it's not the MAP Sensor, and my ECU is not putting out any error codes. My car is idling rough, drives fine, boosts fine... but the inhg are NOT a solid 15. They flux around 13-15 bouncing up and down. THe idle is a bit rough, but the rpms are where they should be... AFR is reading 720-730 with default settings. How likely is it that I Have dirty fuel injectors?? I don't know enough to keep dicking around with it. Should I Have a diag test done on it by MAzda? OR should I keep trying with stuff that might not even be the problem? ANyone else had a similar problem and found it to be the fuel injectors?? Lemme know! THx!

When my car was idling rough, replacing the injectors fixed it right up.

try the spark plugs and wires first, they are cheaper, if it still idles rough its the injectors more than likely

yeah. listen to boostd. he knows more than me.

if it's not the plug nor the injector, then look into fuel filter too.

Changed plugs (WHAT A BITCH!!!!) The old ones had some pretty bad carbon buildup. None the less, rough idle still exhists. About to change the fuel filter... awaiting results on my compression test (get them back in a few mins), injectors eh..? Is there an easy way to get to the fuel filter, its about the differential and it's a bitch... have to remove both pans and whatnot... anyone have any tips?

Remove the two hoses first. Then use a long extensions to remove the two bolts holding the bracket. You don't need to remove anything but it is tough to get at the fuel filter.
