I tested the o2 sensors and here's what I found... The RH sensor stayed mid range-.30-.60 tho it occasionally hit .7 VDC. The LH sensor cycled as low as .12 and as high as .7, but it tended to stay more mid range tho not as much. My Chilton manual says that they can be bad is they stay mid range. But it also says that there should be 2 upstream and 2 downstream sensors and I couldn't find any downstream sensors...
I checked the front wheels and found nothing to indicate any balljoints or rod ends. --- In [email protected], Geoff <geoff.gari...@...> wrote: > > On Thu, Jan 15, 2009 at 11:08 AM, doobletango <maninbl...@...>wrote: > > > 12 Direct battery input to PCM was disconnected within the last 50 > > key-on cycles.
