Preguntas

5 preguntas
Q1

Does the stalling happen more frequently when the engine is warm or cold? (ID: 1680)

It seems to happen more when the engine is warm. I've had it stall on me after driving for a while, especially in stop-and-go traffic when the engine has been running for a good amount of time. It hasn't happened as much when I first start it up in the morning.

Q2

Are there any warning lights illuminated on the dashboard when the engine stalls or before it stalls? (ID: 1681)

No, that's the weirdest part. No warning lights come on at all. The check engine light isn't illuminated, and no other dashboard indicators flash or stay on. It's completely unexpected.

Q3

Have you noticed any changes in engine performance, such as rough idling, hesitation, or loss of power, prior to the stalling? (ID: 1682)

Before it stalls, I haven't noticed any significant changes. The idling seems pretty normal, and I haven't felt any hesitation when accelerating or a general loss of power. It's usually a sudden cut-off, almost like turning the key off.

Q4

When was the last time the fuel filter and air filter were replaced? (ID: 1683)

I'm not entirely sure about the exact dates. I bought the car about a year and a half ago, and I don't think the previous owner mentioned when they were last replaced. I haven't had them done since I've owned it, so it's probably been a while.

Q5

Does the stalling occur more often when the air conditioning is on? (ID: 1684)

Yes, I've definitely noticed it happens more frequently when the air conditioning is on. It seems like the engine struggles a bit more when the AC compressor kicks in, and that's often when it decides to die.
