Need advice: Random misfire code but engine feels fine

This is usually cheaper to test than to guess. Capture voltage while the 2022 Volvo XC90 is actually failing — after it restarts you've lost the clue. You'll know quickly if you're on the wrong tree. I'd want that in writing, not as a promise. Video is ugly but it shows the hesitation.

Intermittent stuff lies if you only catch it once. If a shop can't duplicate it on the 2022 Volvo XC90, bring a video plus freeze-frame data, not just a story. Save the big job until that test fails. On “random misfire code but engine feels fine,” that was the fork that mattered for me. This is from a 2022 Volvo XC90 in Central Florida with 8,200 miles. Was this after sitting overnight? If your situation is the opposite, ignore me. No warning lights, which is why I'm documenting it.

Log the conditions before you spend. Two 2022 Volvo XC90s can feel identical and have different causes, so measure before you copy someone else's repair. If the cheap test changes it, stop and reassess. On “random misfire code but engine feels fine,” that was the fork that mattered for me. This is from a 2022 Volvo XC90 in Central Florida with 8,200 miles. If you share a photo of the worksheet, easier to sanity-check. Trying not to diagnose from the couch.

Log the conditions before you spend. Loaded-suspension checks on the 2022 Volvo XC90 catch play that a wheels-hanging inspection misses. That's the branch I'd chase this week. On “random misfire code but engine feels fine,” that was the fork that mattered for me. Post the numbers (or the code) and people can get more specific. Not driving it hard until I know more.

I wouldn't throw parts yet. Write temp, speed, and in-gear vs coast when the 2022 Volvo XC90 does it — then decide on parts. Save the big job until that test fails. If they can't show the line item, I assume it's hiding. Worth doing even if the car feels fine right now. If this is nothing, great. I want that in data.

If it were in my driveway, if a shop can't duplicate it on the 2022 Volvo XC90, bring a video plus freeze-frame data, not just a story. If the cheap test changes it, stop and reassess. This is from a 2022 Volvo XC90 in Central Florida with 8,200 miles. I'd want that in writing, not as a promise. I'll poke at it this weekend.

If it were in my driveway, swap the cheap/easy piece first on the 2022 Volvo XC90 and see if the fault moves. Don't erase codes until someone who can help has seen them. Learned this the expensive way on a previous car. Wrote this up on my lunch break.

Start with the test that can prove you wrong. Get a real battery/charging test on the 2022 Volvo XC90, not just resting voltage, before blaming a module. Save the big job until that test fails. Was this after sitting overnight? Worth doing even if the car feels fine right now. I'll poke at it this weekend.

Start with the test that can prove you wrong. Move a coil or plug on the 2022 Volvo XC90 if it's cylinder-specific and see whether the code follows. That's the branch I'd chase this week. Stop there until you know. Parking it somewhere I can hear it better next time.

Ask what changed right before it started. If a shop can't duplicate it on the 2022 Volvo XC90, bring a video plus freeze-frame data, not just a story. If the cheap test changes it, stop and reassess. Have you gotten a second quote in writing? If it repeats twice more I'll book time.

Have you gotten a second quote in writing? That's coming from doing this as an owner, not a shop. This is me being the wet blanket on purpose.

OP update: scanned the 2022 Volvo XC90 again and still only have the one pending code, no new lights. Happens in gear, not in park, for what that's worth.

Ask what changed right before it started. If a shop can't duplicate it on the 2022 Volvo XC90, bring a video plus freeze-frame data, not just a story. If the cheap test changes it, stop and reassess. Had a similar mess a couple years ago and that's what finally sorted it. If the story changes I'll post the new data.

I wouldn't throw parts yet. Move a coil or plug on the 2022 Volvo XC90 if it's cylinder-specific and see whether the code follows. Save the big job until that test fails. Post the numbers (or the code) and people can get more specific. Cold start is when I can actually reproduce it.

If it were in my driveway, move a coil or plug on the 2022 Volvo XC90 if it's cylinder-specific and see whether the code follows. That's the branch I'd chase this week. This is from a 2022 Volvo XC90 in Central Florida with 8,200 miles. If it doesn't change the out-the-door or the repair estimate, it's noise. Parking it somewhere I can hear it better next time.

I'd want a measurement, not a hunch. A pressure test beats staring at a dry driveway if the 2022 Volvo XC90 is losing coolant with no puddle. Don't erase codes until someone who can help has seen them. If you share a photo of the worksheet, easier to sanity-check. I'll update if anything new shows up.

It did random misfire code but engine feels fine twice this week, both times after sitting. No change in mileage feel. I'll poke at it this weekend.

This is the filter I use when the thread starts repeating itself. I'm in no rush to be a hero on it.
