| Does anyone know what to expect when replacing the EGR valve? Cost? I think mine needs to be replaced; I thought the exhaust that I was seeing was a blue color but Ive been seeing more of a black ash color and strong raw gas oder from the exhaust,also reduced power, detonation (pinging), rough idle, and hesitation when accelerating. I know I need plugs as well. |

The MO does not have an EGR valve.
Thanks to the variable valve timing the exhaust valves are left open for part of the intake stroke. This allows for some of the inert exhaust gases to enter the cylinders similar to the function of the EGR valve.
I think a new set of plugs may cure your VQ's ills.
By the way, you posted in the "2nd Gen" section, which is for the 2009 MOs. I have moved this thread to the correct section.

| Sounds like to me that your MO is running in a rich mode becuase of some inner problem. Have you gotten your codes checked? AutoZone will do it for free or you can get a ScanGauge and do it yourself. |

Codes are an excellent suggestion.
This could be just a O2 sensor.

Thanks Joe. By the way, Warhammer does the service engine light have to be on to check codes? |

Well ... if his has an EGR valve when it's not suppossed to ... that's a huge problem!!! Just kidding ... I don't even know what an EGR valve is! |

The EGR (exhaust gas recirculation) valve is an emissions control device which essentially recycles some of the exhaust gases back into the combustion chamber during the intake cycle. In short, it helps your car pollute less.
Yes you can check for codes without the light on, but it might tell you much. I would change the plugs first and see what happens. |

Thanks for the info, I made an appt to get the plugs changed tomorrow, the lowest I could find was $237, everyone else wanted $360 to $400; I would change them myself if it were not for the 3 plugs in the back.:3: |

Yeah the three in the back are a hassle to change since you have to remove the intake manifold to get to it. |
