Okay, so i went to do a check-around on the Z today. mainly the o2s. i check the connectors and they look super clean, both (L+R) connectors were slightly unplugged, i fixed that, so inside and out theyre clean. the o2s itself had a little dirt but thats it. (on my ecu diag. i did have code 34, L o2 senor) i turn the car on, and hey guess what?? no rough idle which i had be4, sweet. tho im not sure if thats what fixed it. i take it a step further to see if ive still got my under-powered problem. yea, i do, it feels so slow (mashing the pedal down too) so im still not sure. ive got the knock sensor to check out as well. ...so whatcha guys think its causing the z to feel under-powered and having crappy gas mileage. i hope replacing both o2s and knock s. will fix it.
