Bought the car and has me scratching my head. It s tuning rough at idle and will stall out time to time. I have checked as well as I could visually and spraying carb cleaner to try to locate. No luck. It is showing p0300 and p0134 codes. The 02 sensor is a newer one but I haven't replaced it
If I unplug the IAC on the throttle body the car idles fine with out surging or stalling but in my opinion just a tad higher than normal but a lot better. I know the PCV s are common but I sprayed it well no change in rpms. I'm at a loss for words but I would say it would be a vacuum leak because it sounds like a Leak right around the throttle body area but I don't know if this noise I'm hearing is usual on a mazda 6 or not but I'm hoping there bid someway to tell me for certain for certain if it's a part or leak. Any guidance will be appreciated.
have the same problem?
