Hey i got an injen intake and tenzo r super drag air filter. My check engine light wont go off, i took i to autozone and it says: 'fuel for cyl 1 is too lean' I don't have injector problems so i think i maybe getting too much air. There is this air temp thing that, i think, senses how cool the air is to tell how much gas to inject. Can someone please help me? I can never get the dang thing off.

 

read the manual, it may mean your suspossed to do something. mine was set to go off at around 60,000 miles (to change something related to smog)

 

first off the engine can never get too much air so that cant be a problem you might want to get the air-fuel ratio changed so that it runs just a little bit richbut not too much. BTW what year is the car? If it is a 96-98 give it a few days and it might just go away

 

Unplug the little thermal switch(air temp bulb). Start the CAR and run it for a bit. See how it handles the air mixture..
THEN, Disconnect the Battery, reseat your Throttle Body connector, MAFs connector and Water Jacket, Fuel rail connector. They are all in the Throttle body area. Plug back the air temp bulb.
Let the ride set for a few hrs, then reconnect the battery and go drive it around... Your Problem should be long gone..

 

i was just about to say that
