2013~2016 Sluggish pedal/throttle response, frequently: need suggestions, expertise

[GFrosty]

The pedal/throttle response on my 2016.5 CX-5 GT AWD is frequently sluggish. Need everyone's expertise and experience with identifying all the parts, sensors and whatnot that might come into play, with this issue.

It doesn't happen every acceleration. It doesn't happen in every gear. But it almost always seems to be in a situation where the load is suitably "light to middling" and the RPMs are in the ~1400-1800 range. The car frequently doesn't seem to sense that the load's rising, that my accelerator pedal is being depressed additionally.

I've been toying with the degree and firmness of pressing the accelerator pedal. And while it does seem to be problematic less frequently when I press hard and far on the pedal, IMO it shouldn't be so hesitant and sluggish in responding to increasing loads/pedal.

Am hopeful it's simply one or more sensors and/or parts that are causing this. Need help identifying every last component in the vehicle that could be part of this sluggishness, as I'm unaware of all them.

List:

1. Throttle Body, containing the throttle position sensor -- have properly cleaned the TB and the sensor's contacts, twice in the past year; but haven't tested the signals.
2. Accelerator Pedal assembly (with the included sensors) -- haven't touched this, yet, nor tested the signals.
3. Anything else???

I would prefer that it's some sensor or cleaning that would rectify. Am open to a tuning of the vehicle's performance, though I don't have any performance extras on the car that would otherwise justify such a thing. I just want the hesitant, sluggish response (for dropping a gear when load and pedal angle dictate) to be more brisk and responsive. Like all the test-driven CX-5 vehicles were, when I took them each through their paces.

Is this something new that you're experiencing?

Sounds like the way the throttle is tuned from the factory to me, not an issue. It's tuned this way to save gas and reduce emissions by essentially ignoring or dumbing down your request for additional throttle when conditions for said throttle increase are not optimal.

etc. let's say you're going 70km/h in 5th gear at 1500rpm. you push the throttle harder. you may notice that the throttle doesn't really respond much. this is normal. the ecu is limiting the opening of the plate in your throttle body because it doesn't make sense to start loading up the engine at 1500rpm due to lugging.

But... the AT is tuned so stubborn, and will refuse to drop down to 4th gear at a throttle position which suggests that it's probably best to.

So... simply use manual mode, and drop to fourth gear, which would bring you to about 2000rpm. You should have more "freedom" now to apply additional throttle as needed, with the response you desire.

I purchased this vehicle pre-owned. Generally speaking, to me it has always felt sluggish or hesitant in deciding to drop down a gear when the loads and/or accelerator pedal depression would (IMO) justify a drop down. Instead, it remains in the taller gear far, far longer than I would expect. Most of the time.

It's almost as though the car has been configured to prioritize fuel economy above everything else, at all times and under all loads. That is, unless I mash the accelerator pedal. Even in "Sport" mode it requires a mashing or near-mashing of the pedal in order to get it to kick down a gear.

So... simply use manual mode, and drop to fourth gear, which would bring you to about 2000rpm. You should have more "freedom" now to apply additional throttle as needed, with the response you desire.

Sure, I often use manual mode, when I feel the transmission's being particularly laggy at the moment. But on an "automatic" transmission that seems weak. I would think that it would be far more responsive to accelerator pedal angle than it is.

Which is why I asked the questions. Hoping to hear from people what parts and sensors, specifically, are involved in all of this, such that I can do a bit of further digging.

Have had a 2012 Mazda 3 2.5L with A/T. And that vehicle was downright responsive when moving the accelerator pedal even a little bit. Almost never required mashing the pedal in order to get it to wake up and drop to a lower gear. Wasn't excessive, but it was "how it should be", at least IMO. This partucular CX-5 hasn't ever been.
