Have you cleaned the MAF, IAC and throttle body. The
numbers would suggest it is running rich for some reason.
The MAF would be a likely candidate. There are sites on the
net on how to clean it including pictures.
1. Clean the MAF thoroughly.. directions everywhere.. dont be afraid of
it... use a CLEAN/new med bristle brush and rubbing alcohol. about ten
brush-ons/rinses wil make sure.
2. New primary O2 sensors cant hurt... never had that problem, but then
again, I dont run 'just any' brand name gas.
3. Replace Fuel Pressure regulator
DEFINITELY - Change OIL, run out on freeway for about 20 minutes day
before... then again, within hours before you take it in again.
You have done PCV, good.
Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price
you pay..DEAL with it!
