1998 Lexus LS — ceramic coating is glossy but paint still got light swirls

Log the conditions before you spend. Capture voltage while the 1998 Lexus LS is actually failing — after it restarts you've lost the clue. You'll know quickly if you're on the wrong tree. On “ceramic coating is glossy but paint still,” that was the fork that mattered for me. This is from a 1998 Lexus LS in Tampa with 135,500 miles. Verbal 'we'll take care of it' is not a plan. Doing the boring step first on purpose.

I wouldn't throw parts yet. Two 1998 Lexus LSs can feel identical and have different causes, so measure before you copy someone else's repair. Don't erase codes until someone who can help has seen them. Run the total, not the monthly, before you commit. I've seen both outcomes, which is why I'd test instead of assume. Might be overthinking it, but I'd rather overthink than overspend.

I wouldn't throw parts yet. Write temp, speed, and in-gear vs coast when the 1998 Lexus LS does it — then decide on parts. That's the branch I'd chase this week. That's the whole play. This is the version I'd tell a friend.

If it were in my driveway, swap the cheap/easy piece first on the 1998 Lexus LS and see if the fault moves. Don't erase codes until someone who can help has seen them.

Might be overthinking it, but I'd rather overthink than overspend.

I'd want a measurement, not a hunch. Get a real battery/charging test on the 1998 Lexus LS, not just resting voltage, before blaming a module. Save the big job until that test fails. A shop burned me once by skipping that step. Not trying to scare you — just skip the expensive first guess. If it repeats twice more I'll book time.

OP update: scanned the 1998 Lexus LS again and still only have the one pending code, no new lights. I'd rather pay for diagnosis than a second guess-repair.

Ask what changed right before it started. Write temp, speed, and in-gear vs coast when the 1998 Lexus LS does it — then decide on parts. You'll know quickly if you're on the wrong tree.

If it were in my driveway, get a real battery/charging test on the 1998 Lexus LS, not just resting voltage, before blaming a module. Save the big job until that test fails. Time, temperature, and whether it's in gear are the notes that actually help a shop. I'll update if anything new shows up.

Intermittent stuff lies if you only catch it once. Move a coil or plug on the 1998 Lexus LS if it's cylinder-specific and see whether the code follows.

Ask what changed right before it started. Swap the cheap/easy piece first on the 1998 Lexus LS and see if the fault moves. If the cheap test changes it, stop and reassess. Just my two cents from doing this recently. Might be overthinking it, but I'd rather overthink than overspend.

Intermittent stuff lies if you only catch it once. Loaded-suspension checks on the 1998 Lexus LS catch play that a wheels-hanging inspection misses.
