new o2 sensor
what would cause my block learn to slowly go down
like from 128, ran that way for a long time for over
a year, then real slowly started to get richer down
to 118 this took about 4 weeks this is at a steady thottle,
tried a new o2 sensor
same problem

Re: new o2 sensor
Leaky injectors, fuel pressure increasing, FPR diaphram leaking, fuel has less ethanol in it, bad MAF, bad MAP sensor.
