2000 es running lean mass air sensor
My check engine light has been coming on...i had it serviced today the code was saying the problem is the mass air flow sensor reading the car is running lean. I do have a Weapon R intake on the car. Anyone have any ideas as to what i should do. Is there a way to raise the mixture. Is there a higher performance mass air flow sensor available? Any feedback would be much appreciated....THanks.........

What? You don't tune a car to compensate for a bad sensor...
What are you saying, the CEL was on before you installed the intake?
If the MAF sensor is indeed the problem, you need to replace it, otherwise you are doing damage to your engine by driving with a leaned out mixture.
As far as I know, you can't tune these cars unless you make changes to the programming on the ECU, which none of us have the resources to do.

of course i would not put on the Weapon R intake with a sensor on....Yes it came on after the Weapon R...about a year later. my mas bolts down to the custom intake pipe...maybe i just need a new one....or i gotta put the old intake back on...would hate to have to do that....i do not think i am doing damage to my engine....if i reset the computer some times it takes over 500 miles for the light to come back on....so i think it might be running right at the boarder line...or maybe the sensor needs to be cleaned...gonna try all before i put that ugly box back in the car.

that 1mz-engine is highly sensitive when it comes to the intake system. i used to have both, long and short ram intake on mine and i had p0171 running lean/rich code. EVERYTHING is reassembled to the way it was. there is another topic where other members here modded the stock airbox to fit an intake filter w/o any codes thrown.
