I have a 95 Neon with 400,000+ km on it and believe that the EGR valve is failing. The car at some points, will not stay idling and will stall if no throtle is aplied. Other times, it'll idle at 1500+ RPM, and if I shift gears below 2500RPM, when I press the clutch and release the throtle, it revs up to about 3000RPM before dropping.[QUOTE] From what I have read, this fits for a dirty, or failing EGR valve.[/QUOTE] Is there a way of testing to verify that this is the valve that is failing, and not another problem? I would hate to pay the 5CND for the valve, and find out that is not the issue. If it is dirty, can it be cleaned? Mike mlawrenc(at)gmail.com
