Thomas, This may be your problem. I would fix it first since this valve provides by-pass air around the throttle body . In effect it should raise the RPMs when cold. I always removed it for testing. When cold, air should pass through it freely. I believe you can actually see light through it. Apply twelve volts to it and a disk inside rotates to shut off the passage. Spraying carb cleaner through it and then some lubricant (not WD20) seemed to fix mine for about a year. When you get the valve working correctly you need to set the idle where you like it when cold and make sure it drops to ~850 when warm. Good luck.
