2017 Tacoma 3.5l lean issue. was created by Ora1996
I’m working on a 2017 Tacoma that would not start. slowly pump the gas and got it to idle it has lean codes for both banks looked at data running really lean both banks about 30lt both banks looked at fuel low pressure data desired and actual look good. High pressure actual and desired look good at times but noticed that the actual went way higher than desired. Any suggestions? Thanks

Although it seems like something quite simple, I have some Tacomas with problems with the dirty MAF sensor.

Do you know what the grams a second are supposed to be?

I would expect about 3 to 5 g/s

Ok thanks. That’s what I was thinking it has 2.5g at idle also it doesn’t seem to follow the calculated load very close. I recommend some 44k and a new sensor but the customer is just going to try the cleaner.
