It has not done it again, but i just took the car over to lexus and they gave me a loaner. Covered under the powertrain warranty.... So hopefully they find out what it was..

Curious to find out what it was.. and whether your dealer will say anything about the fact that you have headers, exhaust, etc.

That sound resembles something related to the valves as cover on to tight or a loose valve.

I guess 'yes'. I wonder if some sensor in the exhaust has been corrupted sending the engine controls for a wacky loop

Micaiah

Sounds like an injector is malfunctioning, causing misfiring causing the valve to go wonky.

But I'm just a girl. I know nothing about cars.

The lexus dealer here in nashville is pretty cool, they never see modded lex's so they always gawk at my ride and talk to me about it. All my mods have never been a issue and im pretty sure none of the mods have anything to do with that sound. it was comming from the top of the engine.

Or it could be lifters.

Not sure we have lifters on a DOHC engine.
