screwed the gas cap on...
Check VCs light came on again. The first time it came on, I screwed the gas cap on tightly and it went off for about 2-3 weeks. It's on again.
JA: How has your mileage been lately? How many miles are on the car?
Customer: Not driving a lot lately as I work from home. It has around 165K
JA: Are you hoping to fix this yourself?
Customer: Yes
JA: Great! What have you tried so far?
Customer: Just making sure that the gas cap is tight

Hello. Welcome to Just Answer. Please allow me to assist you. Is only the VSC light on at the instrument panel?

The first time when it came on, I was driving. It acted like it was about to stall so I drove it home. Luckily, I was blocks from my house.

I turned it off and jumped on a few Lexus forums to see what the deal was. Several ppl said it was the gas cap. I screwed it on tightly and it went off for about 2-3 weeks

Lexus forums are, well, just that, forums where non-tech people go who do not know about Just Answer. "Check VSC" does not mean there is an issue with the gas cap. Check VSC means you have a problem with the vehicle skid control; most likely, the yaw sensor on the steering column has lost it's "Zero point calibration'. I see that you also have a check engine light on. This may be a secondary (or primary) issue. You need ot ge the car scanned in order to determine why the check engine and VSC lights are on to be sure if the VSC issue is the Yaw sensor calibration. Most auto parts stores (Autozone, NAPA, etc) will do a scan for free (so they can sell you their parts). I would get the car scanned.

The zero point calibration needs ot be done by a dealership with their scan tool and the necessary software inside the scan tool. It would be almost impossible to have this done outside of a Lexus shop

Ok, thanks. A buddy who owns Lexus (Lexi?) just told me to put this stuff called B-12 in and fill it up with premium gas

Absolutely not. Waste of time and a lot of money.
