ive got an 89 gt, i put new injectors in a cuple weeks ago, along with a new MAF. but now after about 20 mins of driving the MIL comes on. so i hooked up the scanner and it says that im running lean. im confused as to why it would start running lean so long after driving. i can let it idle for forever and the light doesnt come on. any ideas as to why it is coming on?

 

Faulty O2 sensor??, may unplug the battery for a while and see if the computer will relearn the new injectors.. could one of the o-rings have come off one of the injectors on the intake side, allowing air to enter , or other intake leakes??

 

great ideas ^^^^

 

alright thanks man, ill definatly take a look at the o2 sensors and try the battery idea. if not then its gotta be the injector or a bad seal on the intake gasket i guess
