2023 Toyota 4Runner — going one inch smaller for winter wheels

If it were in my driveway, move a coil or plug on the 2023 Toyota 4Runner if it's cylinder-specific and see whether the code follows. If the cheap test changes it, stop and reassess. This is from a 2023 Toyota 4Runner in Seattle with 23,500 miles. That's the whole play. I'd sleep better after that step, even if it finds nothing. Next check is the cheap one I can do in a driveway.

Ask what changed right before it started. A pressure test beats staring at a dry driveway if the 2023 Toyota 4Runner is losing coolant with no puddle. That's the branch I'd chase this week. Keep sale price, fees, and rate as three different conversations. That's coming from doing this as an owner, not a shop. I keep a notes app thread for this now.
