got comp numbers for my 200,000 mile 3vze today. driver f to b 170 150 170. pass f to b 175 175 170. seem pretty good to me. i had the hg done under recall about 70k ago. and other than that, i have done nothing but maintain it. so i'm pretty happy.

i am getting a code 25 - lean condition. don't know why. truck runs great, plugs look good, o2 sensors (before and after cat) have just been replaced with denso units. any thoughts on that would be appreciated. the only thing i can think is that my stock air box just has a big hole in it, cuz i took the plastic pieces out that route it behind the light. it tripped the ck engine lt within a short time after that. don't see why that would have anything to do with it but that is the only thing i changed around the time the light came on.
