Quick question about maf on 97 runner
I have a toyota pickup with a 3.4 from a 97 swapped into it. I tested my maf both ways I've seen that it says to. Such as applying air with the meter hooked up and look for a voltage fluctuations which there is. I tested the resistance at full operating temp and it came back at 2.7 ohms which according to the book is out of spec. Any suggestions? The temps that it lists next to the appropriate ohm readings kinda confuse me

Without digging into my FSM and getting out the specs to compare with your readings .
I don`t know
If the numbers don`t match and your meter was in the correct range .
You have to draw your own conclusions .
Just what code or codes was the OBD II system showing ??

It showed a cam positioning sensor so I replaced it yesterday with no change. I've replaced the coolant temp sensor and both o2 sensors as well. The issues is only when the truck warms up there will be a bad lag in throttle response on a take off from a stop. Tps tested out good and I have already cleaner the iac,throttle body and maf. So with the readings Im getting from the maf I think it could be the culprit Im just having troubles with my book. It says at 176 degrees it should be 0.2-0.4 which is definitley not what I got when I tested it after the truck reached full operating temperature

You need to remember that a code is the complete circuit for that sensor
The sensor the wiring to the ECM and the ECM
Could be something as simple as just a corroded connection.
Most times when you get a lack of signal from the cam or crank sensor the engine shuts off because the injectors are shut off. A safety measure to keep from dumping fuel into a non running engine.
If it did not I would think about the ECM
You ECM did not get wet did it ?? Just where is it mounted ??
