Anyone ever had a problem like this? I only have 55,000 miles on the vehicle. Let me know what if any details I can provide to help diagnose.

  • Never noticed the problem happening when coasting; as far as I can remember it's always:
  • When at a stop/low speed
  • When I'm accelerating
  • When cruise control is on
  • It feels as if it's randomly low on gas.
  • If it stalls and shuts off when I'm stopped, it'll usually struggle to turn back on.

Welcome to the forum. No codes? No 'ck eng' light? Any misfire? Was the car in any flood?
This will need diagnosis. Troubleshooting may be more difficult without fault codes, but not impossible.
A data recording of a stall may help a service technician see what is or isn't happening.

Bad grounds & corroded terminals in the engine compartment of a 7 year-old car is possible.
A test drive with a good scan tool watching inputs/outputs may point to something that doesn't seem right.
Look over the engine compartment wiring for issues.

At stops & low speeds, fuel demand is low, but I have driven a car with a fuel pressure gauge under a wiper blade for monitoring fuel pressure on a road test.

Nope -- no codes, no check engine light, and no misfires that I know of (though I'm not confident I know how to identify a misfire). I've been keeping more meticulous notes recently to help my mechanic narrow down the problem; I'm hoping to call him today with what I've gathered. I'll give an update once I have one!

Let us know what is found. If it can be experienced & demonstrated, it can be diagnosed. A good scan tool that can see what the PCM is seeing may give some insight to what is occurring.
Sorry I'm not much help. It could be several different things. A vacuum leak? Throttle body problem? Fuel Pump?
Bad grounds or connections? (Either an electrical (ignition) or fuel problem)?
Without a fault code or other diagnostic clues, it is hard to point you in a direction.
Did this degraded performance, stalling or hard starting happen suddenly or was it something that got worse over time?
