ok steve here is the latest.
meter connected to o2 sensor while driving varies
at idle 8.89. connected meter to eha valve=9.87
then when i disconnect the o2 sensor it drops to 2.35to3.45
ok now connected everything back to normal sampling the o2 sensor like you said at 2000rpm i adjusted the mixture screw
to 5.67to 6.98 and at idle it goes back to 8.89 but know the car idles like **** with a miss to it and hesitate while trying to rev up motor. if i bring it more toward the rich side the miss goes away idle is good and barely any hesitation any suggestion as what to next.thanks jose
