Maybe mechanic drink too much Soju and think he is a parts replacer.. First thing, like already mentioned, mechanic should have run a scanner testing for DTC's as this fault triggers the CEL. Also, he should have performed a spark test on plugs and coil packs prior to replacing if no misfiring codes were present or to isolate problem cylinder misfire.
Hopefully OCV will fix the problem...it's a 10-15 minute job
Looks just like the engine shake on my Hemi 5.7 that set for 1 year and the fuel went bad..Forgot to put fuel stabilizer in fuel tank.

Weird, indeed...
VTEC (Variable Timing and Lift Electronic Control) is a system developed by Honda. It is drastically different than the Toyota VVT-i (variable valve timing with intelligence) used on the LS430.
Perhaps the "scanner report" the technician presented was for another car.

I have a Honda Acura with VTC and LS430 with VVT... Different nomenclatures, similar functioning systems. Perhaps mechanic is more familiar with Hondas terminology than Toyotas.
EDIT: I stand corrected," Basically same thing" is a false statement in terms of operation.. Different technologies, however both have to do with timing of the valves.
Just proves I'm not a mechanic...lol

Hello. everybody.
Mechanic are show up check report to me.
1. motor mount
=> is ok.
2. coolant temperature sensor
=> is ok.
3. spark plug and IGN coil
=> is ok.(replace all spark plug and IGN coil)
After use a car scanner, found "VTEC system fail" code.
My Mechanic said to me. will replace "OCV valve".
Almost "VTEC system fail" code is can repaire that replace "OCV valve"
I'm just waiting the this work.

...and if you ever wondered what this VVT-i (Variable Valve Timing with Intelligence) is about, and how it relates to the OCV, check out Post #2 on the following link https://www.clublexus.com/forums/ls4...ml#post8880322
