oh its a government conspiracy! i bet the army did it! they like to change things every year just to mess with you!

 

I appreciate everyone's help. I've finally located the PCV valve at the rear of the driver's side valve cover! That was weird; I downloaded the 3rd generation service manual from this forum and also have the Haynes manual and both show the valve on the oil filler tube.

For the ocassional rough idle and abrupt stalls, I'll look at replacing the MAP and throttle position sensors, that's easy enough to do. I may consider having the dealership hook up and test the cam and crank position sensors. The service manual I downloaded from this site even talks about backprobing those sensors with a bench scope and watching the square wave signal as you tap the sensors and wiggle the wire harness, etc.

These two issues seem to be two separate problems, and the summer time heat seem to make it worse. I already replaced the IAC idle motor and the ocassional rough idle did get less severe (used to really cough and sputter), but once in a while I'll feel it in the seats and see the RPM needle dip a little over a 100 RPM and come back up.

 

well replace the map sensor and see if your problems get better!

 

Make sure you use Mopar parts. Ive had several TPS sensors and nothing works like the Mopar one. BWD does make the Mopar IAC which is available cheaper online and at Advance Auto, but all the TPS sensors are different from Mopar. They dont give the same values and have actually made my idle issue with my fastman worse. Just order the Mopar one and save yourself money in the long run.

 

Does it just pull off of the blue thing? I think I found mine, but all I could see was what looked like a small blue nut (i'm assuming its just the PCV Valve fitting over the blue thing in the picture). I haven't yet bought the replacement and can't see exactly how it goes on. I wasn't sure if it just pulls straight off or if you need to turn it off? Didn't feel like breaking anything tonight :-P

Also, this picture is deceiving. There is alot of other junk in the way that is not in this picture. Hard to see it at first glance, but par for the course I guess with all the electronics and emissions stuff on vehicles these days.

 

Mine is on the filler next for the engine oil, but since this is the only picture I could find that came close to showing the location we sure could use some better pictures of the location! *Cough* *Cough* *Hint* *Hint*

 

I'd like to thank you for doing the research and getting us all this picture as well. It got me a whole lot closer than the filler neck that I was looking at to begin with. I will try to work on a more life-like picture of the location. lol! Without your pic I would have been totally out in left field with this.

 

On my 06 slt hemi the valve is located right beside the throttle body, you must take the cover off to see it.

 

Revived from 2011?!!

...but out of curiosity, has this been fixed? I have an occasional rough idle, and the truck has flat out stalled on me twice.

 

Has what been fixed?
