Car is hunting for idle Car has started to have an up and down idle at stops. It can not seem to find a steady idle. I have a air fuel ratio meter and it fluctuates between yellow and red (yellow is nominal and red is lean) doesn't ever get into the green area. I pulled the o2 sensors and the left was whitish brown and the right o2 was a darker brownish red. What do you guys think. I tried to reset the computer and make it relearn itself to no avail. Thanks for the help

No codes, I ythink when they reprogrammed the pcm they eliminated those faults. I know they eliminated the emmissions and rear o2's. I try to unplug sensors while the car is running and no light comes on??

If the K&N isn't over oiled it doesn't cause problems. I have 3 cars with MAF's, running K&N's in all 3, never had a problem with the maf getting dirty.
