2013 limited idle problem

[brushnock]

Anyone ever figure out the idle issue when heat is on auto or ac is on? Runs great till you put heat on auto or turn ac on at a stop almost stalls but never has yet

Welcome to the forum!

Which engine do you have, 2.0L EB, 3.5L NA, or 3.5L EB (ecoboost)? It would be good to include that info in your sig or member profile under the "Trim Level" section.

I faced this once on my '14 with 3.5L NA (not Ecoboost) when it had a bad tank of gas, but there is a TSB for what this might be, that engine isn't increasing throttle enough when cycling A/C compressor on, so sensing the drop in RPM, it immediately disengages the compressor and RPM picks back up.

IF that is the problem, there is an updated firmware for the PCM to address this, that a Ford shop can install but it is not a recall so not free to do.

See my post #2 in this topic for more info and a link to a youtube video:

2013 Ford Explorer Idle issues

Hello So I have a 2013 Explorer XLT 3.5L 2WD and sometimes when I am in park I have a cyclical RPM drop and at least once the car has completely died when it dropped. I have a check engine light for a P0430 code bank 2 Catalytic converter. This part has been replaced twice but I still get the...

Sounds like it's going to stall while idling

I have a '13 Explorer Limited with about 19,000 miles. I'm currently traveling and about 4 hours away from home. On the way to my destination, my car sounded like it was close to stalling while idle and the lights in the car would dim during that time when it was about to stall. It never did...

I don't recall that nor was I able to find the post.

Another more universal problem could be that your compressor is failing, so too much load at idle when the HVAC system tries to engage the compressor clutch, but if it seems to work okay when given light throttle, then I'd lean towards the PCM firmware update being the solution, again if it is the 3.5L NA engine, and being one of the affected 2013-2015 model years.

Just for the heck of it, I'd see if I could replicate this with it parked and hood up, just to make sure that when it happens, you aren't having the compressor seize up and the belt slipping, but if that happens it may only do so for a moment at a time, because that PCM firmware issue I mentioned, is evidence that the system will disengage the compressor clutch if it senses too much engine RPM drop.
