I think I may need an new MAF but don't know how to test mine...
If you know how to test it other than swapping it out for another let me know, very interested.

However,
this post is more on trying to find my replacement.
I have a 1997 SC300 with the Aristo 2jzgte swap..
rumor has it the GS300 MAF is the exact one needed (98+)
Any other vehicles that would have this?

Post #6 says any
"Any car with the VVTi 1UZ between 95-98 used the 22250-50060 MAFS

Same with the 96-2000 JZX100 VVTi 1JZ"

Which vehicles should I be looking for to grab my replacement out of?

 

If pete says the gs300 one worked for a 2j then it works. Being in florida, call Grip industries and ask them. They're very knowledgeable about vvti swaps.

 

PS, think I have one of those MAFs in my back seat I'll never use. What's it worth to you?
