Indeed I am. Sorry; I just got done doing a bunch of throttle body stuff so I thought I'd say something while it's still fresh in my mind. Interesting to know about it controlling the idle with the AC on...my truck doesn't have AC or power steering so I guess I'd have no way of knowing.

There is another sensor that sends a signal for the power steering, it's on one of the power steering lines.

Thanks for your reply. I'm going to look at the linkage and stuff over the weekend (if I get to it ! LOL)

My engine is doing this again the last few days, for the longest time after I started this thread it stopped doing the high idle but this last week, maybe 3 out of the 4 days I went to work it did it again.

Just a quick refresh of the issue:

I drive 36 miles to work, I drive the turnpike and am usually running 80-85 MPH, when I finally get to my exit and stop for the stop sign and put the clutch in the idle will stay around 2000 RPM. Once I take off from the stop I don't notice it again until the next time I come to a stop. Revving the engine does not bring the idle down.

Planning on looking at the TB and related parts today but anyone have any other ideas?

I'll check for codes also,this does not happen every time I drive. For example, on my way to work it did it, but on the way home it did not ??


Thanks all.

Try cleaning the MAF. If the heated element is getting dirty, the ECU doesn't know when your air intake is slowing down.

I picked this up in July 2015:

https://www.amazon.com/gp/product/B0091KCH6U

I use one can to spray a little down the throttle body area of the MAF to melt the "fuel rosin" off and the other can to drench the little heated wire.

That kit gets some bad reviews because of how little contents it includes, but I have sprayed those areas of mine down once a year since then, and I have not used half of the contents. I keep expecting the pressure to be gone out of the cans, but they are holding up well.

Nothing ever really looks dirty, but my idle calms down, my throttle response becomes a little more crisp, and my fuel mileage goes up by 1 mpg for a few months.

Cleaned the MAF sensor and TB today, also cleaned the oil out of the air filter housing, cleaned the hose from the valve cover to the air filter housing and the little breather filter,

Have to wait until I drive to work to see if the idle problem is still there.

Took off yesterday so no long drive but today the idle dropped down to where it is supposed to be, so I guess cleaning the MAF and the TB helped. I'll keep an eye on it over the next couple days.
