Engine/Transmission (1998.5 - 2002) Intermittant Hot Fast Idle Problem

[mhenon]

Intermittant fast idale

I have had this same fast idle problem (if it really is a problem) about two or three times now. I replied to a tread on engine idle

that my engine did this on its own, so it should be possible to make it do it without a fast idle kit.

Mine occured similar to what you have decribed: towing at interstate speed over an extended period of time. When I went to park the rig I noticed the idle up to 1100 or 1200 rpm. Tried revving the engine a little to see if it would go away but no luck.

I made a note in my log of the event and thought I would check with the Dodge dealer next time I was in town.

Well, at start up the next morning... normal idle speed and no more problem. This series of events happened, like I said, maybe two or three different times. It hasn't happened again for the past two months.

I don't think its a big deal. These new rigs are run entirely by computers and if you have any expieriance playing with computers you know they get confused sometimes. Call a computer tech and one of the first things he'll ask you to do is shut the thing off and re-boot. Problem gone!!!

Anyway, thats my two cents worth. My pick-up is stock 2002

and now has 11,000 miles on it. My wife and I are spending the winter touring through Mexico and towing a 25' airstream trailer. What a way to break in a new pick-up.

Good luck, and if you find out anything on this glich, let us know.

Anybody have any luck with getting this fixed. Mine still does this, but only after running for longer periods of time and so far only with the CC engaged. I notice this when it happens because there is no E-Brake action because of a higher idle speed. Sometimes the idle speed will be as high as 1000 RPM, but even a smaller increase will prevent the E-Brake from working. I asked once at my dealer, but of course the problem wasn't present, so I am still waiting to roll into town with the condition present AND during dealer hours.

My 2002 ho has done the same thing, started at 4000 mi. in cheyenne wy. had run 180 mi on cruise. each time it has done this its been on cruise. (about 6 times from 800 rpm to 1200 ) anyway i started turning the cruise off instead of using the cancel mode and it hasn'nt done it again i now have 8800 miles on it.

i am real proud of my mileage have averaged 20. 5 its a 4x2 :

The cure may have found. See this thread in 3g section



Sounds like a 2G APPS design problem.

APPS Replaced

Had my APPS replaced yesterday, with updated version from STAR. Hopefully this will fix the problem.
