TOYOTA 1

no it looks like the 3.slow

Is it possible for you to get an air fuel ratio, and post it up, because im VERY concerned you are running lean and will do irreperable (sp?) damage to the motor.

Some of the air meters look the same but work differently.
IE. some vary the resistance up and some go down as the flapper opens.

Its easy to test this but you need to make sure it is the same as your stock one.

I would pull your plugs to see if you're leaning out.

So it will only work on a 3.0 huh..

I wonder what you could swap into a 22R(E) and do an increase? An older Corolla 20r/22R?

x2 i want to know if you're leaning out! get back to us ASAP

If the new AFM was making the truck run lean wouldn't the O2 pick up on the lean condition which would tel the ECU to add more fuel?

Bumpin' Yota

if im not mistaken the flapper door kicks out a reducing voltage as the cfm increases on the camry vafm. The 3vze's is normal and does the opposite..........

you should definately check to see if you are leaning out

Or get a voltage meter and have someone give it some gas.

js9924

In theory yes but it can only do so much. The AFM is directly linked to EFI and has a huge say as to how much fuel gets sprayed. Plus the O2 is probably old and dirty.

also if it is giving a reverse signal the little difference the 02 will make is insignifigant compared to the huge difference it will make when the ECU is reading a signal that is way off what it should be.

im gona check today if i get a chance and see how the plugs look and compare and try to take a picture if i bring my camra. i put a new o2 sencer in a a few month a go

95RunnerSR5

progress?

just a 22re

ok if it goes backwards like voltage sweaps from other then stock then how would the truck run at idle? or even at wot? so i think that he is running fine but y\ehy its better to know now then later with a new motor and a flat back pocket

Hmmm, If it does run lean would it balance out a bad o2 sensor running rich. Wishful thinking, but then again hmmmm.

Bumpin' Yota

if the voltage is backwards it really shouldnt run at all or at the very least throw a code after the ecm starts ignoring the vafm's output. But hey I could be wrong about the vafm.

js9924

That is a good point but consider this too: The opening is about 1/2 inch bigger thats alot more air volume to cope with. I dont know if the stock ECU can handle that. Like you said better to be sure.

I know that as a fellow 3.0 owner I would love to have a cheap way to have her breathe more with minimal modification. Plus they run a little rich anyway.

just a 22re

ah yes a lil more air and she might get confused lol. to fix that is easy up the fuel pressure a lil to over come it or just a lil bigger injectors maybe but then again more fuel and air means more money at the pumps but i think i can over come that as my rig now runns really rich but yet again its just a 22re

95RunnerSR5

dirtpup where are ya? we's needs updates haha

myyota

If everybody is worried about the engine running lean with the new AFM and possible different eletronics in it, then you could swap the electronics from the old AFM into the new one and it will work just like stock.

bigtrucknwheels

good call haha

JCM4x89pu

no it won't, it would let more air in than the sensor would read, and you would have the same problem.. not to mention how much of a pain in the a$$ it would be to swap the electronics.

instead, you would need to adjust the camry AFM.
