Running Rich Y?

[CNULTR]

Hi guys and girls, my VY V6 is running rich :bang: i dont know why and i was wondering if any one could shed some light on why it is ?Its got Pacemaker Extractors and rear resonator is off, Cold air intake setup stainless steel piping. Could my o2 sensors need replacing ?
Cheers

How do you know it is running rich?

Its wasting alot of fuel also it smells rich outside the car im roughly getting about 300-350 out of a full tank......

Have you had a diagnostics done?

 

[taztassio]

clean your MAF sensor with contact cleaner, and if u have an oil filter (k and N) clean and LIGHTLY re-oil

havnt had a diagnostics done would i need the dealer to do the tech 2, taztassio i might clean my MAF sensor but it looked clean when i had last seen it how ever the K&N filter is new...

The oil from the filter coats the MAF wires and throws out the readings. The ecu chucks in extra fuel to keep her safe when this happens and you lose power too. Might be the case with yours. O2 sensors will also give the same effect but the MAF clean is a much cheaper option to try first.

Is the MAF plug making a good contact?

hmmm i did realize that it wasnt responsive the way it was ,the MAF plug is making good contact, i cleaned the MAF and the throttlebody how ever it looked clean i also disconnected the battery for bout 2 hours to reset the ecu, ill see how i go with it for the time being.

Thanks guys
