Message: [QUOTE="Cat_rebel, post: 137697, member: 90"] I've had a chip malfunction before & it would randomly resort to #5 position which was 1100rpm high idle. Start the truck up & it would rev right up to 1100rpms. Shut it off & restart & it might idle normal or it might go right to 1100rpms & not leave that position. I got a new chip with the same tunes & never had another issue. But a 40° cold start at 1100rpms will always wake you up in a hurry. The biggest issue I see in running your idle at 1100rpms is unless you have a manual you will be fighting your brakes with an auto. My IDI had a cold advance where it would idle up to around 1000rpms when you cold started it & tapped the throttle. I would pop out within 4-10+mins, got tired of trying to drive with hi idle so it was unplugged then the actuator met an angle grinder because it was always in my way. [/QUOTE]
