5th gen surge

[MMETT]

I have 2022 TRD OR. I just put 4:88 gears in ( which may be unrelated) but while crusing at various speeds, I have this weird split second surge like I hit a massive wind gust. No lights or any other issues. I’m lifted, 33 in tires, TRD intake and magnaflow exhaust. Any suggestions at what to look at.

Since you haven't had any response where you posted originally, I'm moving your post to the 5th gen section where you might get some.

Reminds me of a misfire. I'd pull codes (could be pending codes which won't cause a request to turn on the money light) and also check mode 6 data. It will show you the misfires per cylinder for the current drive cycle and the moving weighted average of the last several drive cycles.

wouldn’t a misfire throw the CEL?

Eventually, but not always. It's a 2-trip logic to flip on the CEL. I've had misfires that you could clearly identify and the CEL never went on (but the computer had the codes as 'Pending')

on the misfires you can use carista app with a obd2 dongle. Would need to be under live engine data to monitor the cylinders, and it'll show misfires. If so change spark plug and maybe coil pack. Can always test which one is bad by swapping to another cylinder.
