Default Celiac bogging upon acceleration

Every now and then, not too often, my car will bog and be a little hesitant when accelerating. It will go away shortly, but this is happening more and more. It happened when I was on it once, and the car got quieter, bogged and kinda made a burble sound, but then went back to normal shorty. It doesn't really happen or just isn't noticeable at high rpms (if) it does it.

Engine is rebuilt, only happens down low and not 100% of time so I don't think it's too internal, but annoying non the less. Have a code for Cat converter but that would happen 100% of time right?

Yeah, CAT issues won't be intermittent. The car isn't throwing any other codes? How old are your coil packs? Spark plugs? Injectors? Fuel pump?

Clean the MAF sensor also.

It could be that the cat is partially plugged and that too much exhaust flow causes the bogging down.

Mine has had this issue for many years, only an issue under heavier acceleration.

Likely dirty or broken MAF sensor. Swap in a known good MAF. AFAIK most Toyotas and Lexus use the same DENSO MAF.

Disconnect the battery negative terminal to reset ECU values then test run the car with hard acceleration.

It could be caused by leaky or disconnected vacuum lines around the airbox and the throttle body. Make sure they are all connected and in good shape.

It could be a dirty throttle body. with engine running, spray cleaner into T B while jacking the throttle.
