hi how's every body doing i have question on what type engine oil and transmission oil should i use to do the maintce on the lexus is 300 and what type of spark plugs do ya recomend.

Fuel filter? Air filter? Plugs?

Any more detail on your issue other than lag?

well this is what it happens every time i stop on a red light or stop sign when i step on the gas slowly it responds good but when i step on the gas hard the car don't go no where it gives rpms. the cars responds when it hits 400 rpm or 500rmp. thats only when i step on the gas hard ,when i step on the gas slowly the car is fine.

I would use electronic parts cleaner or they also have MAF cleaner at the auto parts store.

Heres the location: ( Don't mind the red arrows, I was showing someone else the location of some 02 sensors.)

do you have any idea what else can it be.

well i clean the MAF and still does the same thing it still lags when i step on the gas hard do you have any idea what else can it be.

The only MAF sensor cleaner that you're likely to find is from CRC. Just be gentle with the MAF its very fragile.
