We need the exact code that was reported.

Once you have the code, look in the stickies and you'll find some tips, also search: http://forums.maxima.org/search.php

Sorry, i did not explain, I have no codes, the test is when you put the ecm in to test mode II, (i think) and then you start the car, then the ecm monitors one of the front oxygen sensors, you can then turn the ecm the clockwise to switch oxygen sensors and if the MIL does'nt light up 5 or more times in 10 seconds on either sensor then you are running lean.
any body know wut else besides change the oxy sensors, check coils and injectors?
thanx for the reply

well since the car has o2 sensors the fuel mixture relys on good signal from them. older o2 sensors give bad readings. you really should start there.
