Valve Timing Unveiled Mastering the RGA Valve's Rhythm

Think of it as a recycling superhero for your car! Learn how an open EGR valve can lead to rough idling, sluggish acceleration, and poor ... ... EGR valve - auto scan below. Does the ... I can't recall the exact name of the test but it verified the valve closed > open > closed. Open the valve. This will momentarily raise the vacuum pressure. When the pressure stabilizes, close the valve. The RGA should now be kept under high vacuum ... My 93 6sp vert (157K miles, Cats replaced about 30K ago) failed SMOG - High NOx and I suspect the EGR system. EGR valve holds vacuum, ... or does it close when vacuum is applied ? most EGR valves opened and allowed exhaust gas to enter intake manifold, when the EGR valve is ... From my understanding the tune should keep the EGR closed. I seem to ... Egr valve have been known to leak ( open) under pulling. Recirculating the exhaust helps cool the engine cylinders, resulting in less NOx gases. The EGR Valve opens and closes to control the flow of the exhaust gas so ... This IPM employs an open-source RGA mounted ... The high sensitivity of the RGA detects air leaks originating in the process chamber when slit valves are open. When the EGR valve isn't working properly, your vehicle can start releasing those nitrogen oxides and pollute the air. The symptoms of a ... They replaced a sensor which tells the EGR valve when to open or close and it took care of the problem. I guess the sensor was keeping the ERG open all the ...
