Idle discrepancy/question

A small but noticeable issue has arisen with my 2007 manual transmission TRD OffRoad.

Even when warmed up, the idle stays at 1200 until the truck rolls to a stop, then drops to 800. Of course, this is with the clutch fully depressed. I've never encountered any issues with any manual transmission vehicle where the idle had anything to do with vehicle speed.

Any thoughts out there?

 

sounds like the emissions control burning excess gas. others have complained about the RPM jump when shifting which is along the same lines with the emissions control. dam DBW design.

 

I have noticed that too. Always wondered about that.

 

Just got back from the dealership.

They test drove it with a laptop and it's not throwing any codes nor is anything looking out of place. They checked the throttle position sensor and anything that might affect the increased idle.

I'll just keep an eye on it and continue to update if anything else comes up or is discovered.
