Idle issues
Hello everyone I have a 2006 Ford Ranger sport with a V6 3.0L and I have some idling issues when I’m sitting in a parking lot after driving it for a bit it shakes bad it feels like a misfire but there’s no codes I have replaced coils and plugs and plug wires in the past and I recently changed the air control valve i don’t know what it could be

24 hours & I see still no replies, so will see if I can get things started & maybe 3.0L wise folks will chime in. Did the problem come about suddenly, after some event??? You say no codes but I have to ask if the PCM has actually been scanned, or is it because the CEL hasn't been, or isn't now lit????
If its been scanned & no PCM codes are stored, when its idling really rough, is the CEL flashing???? If not, use, borrow, or come by a scan tool that can perform a "cylinder / power balance test", like a Actron CP9145, or 9150, or other model, or brand, that says it can perform a cylinder balance test. It does this test by selectively de-activating each cylinders fuel injector & measuring the RPM drop, so will flag a cylinder with low rpm change. Then we can go to that cylinder & begin our trouble shooting, for a Mechanical problem. Like checking for untoward mechanical noise, like a sticking valve, or maybe a leaking head or manifold gasket, or defective or loose spark plug, a burned valve, or recessed valve seat, which the 3.0L is known to suffer from. & a compression test could be of value to confirm. Some beginning thoughts for consideration, let us know what you find.

What do you define a "scanner" as & what do you want a "scanner" to be able to do???
On my OBD-2 99 Ranger, in 2013 I opted for the inexpensive ELM327 scan tool dongle, that pugs into the in cabin DLC connector under dash at the steering wheel & running FORScan diagnostic freeware on my viewing device choice, as discussed here. https://www.ford-trucks.com/forums/1...-scantool.html. This inexpensive but powerful combo can query All of the vehicle computer controllers for trouble code clues that can help focus a trouble shoot. I've not looked on the FORScan website lately to see if the latest test mods can perform a cylinder balance test, if your interested in doing that too. But the ELM / FORScan combo is a Very good trouble shooting combo on everything else for OBD-2 diagnostic Fords & its inexpensive, so is a good bang for our bucks & a nice addition to our "Electronic Toolbox". Guys on this forum & on the TCCA Taurus forum give Amazon vendor BAFX a thumbs up on their ELM scan tool offerings & their before & after purchase ELM support & warranty,
