So I have a 1991 22re 4runner and i havent found anything on testing the actual wire comint into the mas (mass airflow sensor). I have been slowly working on this runner for awhile now and i have already testen a new ecu and thats not the problem. I replaced the motor and havent quite had it running properly since. I can get a new mas for 85 but i want to check the wiring to the mass before i replace it and have that now be the problem. Also if anyone has one that I can test first that would be great. I can pay for shipping or whatever. Need some help guys!!! Let me know if you need more info!

Thanks for the FSM. I tested the maf and it doesnt seem to be in range. I am ordering one tomorrow for 85$ and hopefully this one will work. I am hoping that this and a little tune up is all its going to take to get my baby back on the road. Thanks. If anyone has a maf i could buy let me know. 22-re 91 4runner.

 

Got the MAS and life is good It worked and I am so happy. Just fixing the last few things up on my build. (or rebuild should I say)
