hey, were is supose to be the mixture on a gslse. mine in idle is rich and when steping on the gas,wile letting the gas of is not marking nothing. that good or not.

 

You're good. You're supposed to be running rich when on the throttle, and bouncing all over the place when cruising. When braking (or just letting off the go-pedal) you should actually be running lean, because thats the way Mazda wanted

 

ok, i whasn't sure. thanks

 

but that still dont answer, does in idle has to be on rich. and now i have the problem that in idle sometimes start jumping betwen 900 and 1200 rpm.
