Im having issues "intermitently" with my idle searching very similar to an
IAC valve going bad, I have already replaced the TPS and the IAC valve
it still does it.... I also cleaned the throttle body...
Would the map sensor cause this problem? What could it be?

 

is your break booster line secure? When i took mine off to throw some seafoam in i noticed my idle was fluctuating

 

Checked all vacuum lines..

 

how much idle fluctuation or problem are we talking about ?

 

You can be driving along come to a stop she will fluctuate about 500 rpms for about 2 minutes then she may settle. Or put it in park after driving and she will continue to fluctuate about 750 rpm for as long as 5 minutes.

 

that's a lot.
and a new TPS and IAC made no difference ?

 

Not a bit!!! I have no engine light on either. I took it to a shop last week, they scanned it found no codes. in the next day or so Im gonna take it to a place where they have an engine analyzer and see what they find...

 

Dropped it off at the dodge dealer this morning they couldn't duplicate it. They did hook up the DRB III scanner and found nothing checked for vaccum leaks from the lines and sprayed down the intake, found nothing.... They didnt charge me since they couldn't find anything..
Anybody have any ideas on this one????

 

the camshaft position sensor will give you a screwed up idle along with the iac. when mine went bad it was idling bad for a couple days then finally turned the check engine light on. its the plastic ring with a wire on it under the rotor in your distributor. just take the cap loose, pull the rotor button off, and lift the sensor right out. you just have to be careful not to pinch the wire with the cap when you put it back on. give it a few days though, and see if it turns on your CEL just to be sure its that. advance calls the camshaft position sensor a pick up coil. i got mine at the dealership because advance had it listed under a different name.

 

Mines does it too. Did you ever find out why
