🔧 YUNDA Replacement EGR Valve with ONE Gasket for Buick Cadillac GMC Isuzu Pontiac V6 V8 - EG10026 EGV589 12576918 4F1139 EGR1067 Review

I wasn't expecting the EGR valve to produce this kind of stuttering, but from what I understand the computer was trying to close the valve but it got stuck in the open position, gave a code and blew exhaust gas straight into the Inlet. The stuttering was terrible at low speeds and freeway speeds under acceleration…

Works great in my 2000 Cadillac Deville. I got rid of my P0404 and P0101 codes and recovered the lost gas mileage. Be sure to use the correct ACDelco Gasket as the supplied gasket seems pretty crappy compared to the quality of the ACDelco Gasket. Will definitely update if it goes down in the near future or something. Edit: Now a few weeks later my car is running much worse than it did with my old dirty EGR valve. I asked the dealer to take a look and they told me that the EGR valve was the…
