it all started with a P0131 O2 Sensor Circuit Low Voltage Bank 1 Sensor 1 code. in the last two months it has not left the drive way as soon as it is put into drive and any throttle it applied it bogs down and starts to back fire, most of the time it runs fine in park. can hear what sounds like a vacuum leak while engine idle but cannot locate.thank you for and help in advance.
everything that has been replaced/inspected:
AC Delco spark plug wires(they were 3 years old and #2 was not sparking)
AC Delco spark plugs (3 years old and bad)
fuel filter ( had got some bad gas and clogged filter black fuel and particles came out of filter)
checked and cleaned small amount of debris from fuel pressure regulator
BOSCH Oxygen sensor B1S1,B2S1,B2S2
water pump (went bad)
AC compressor (went bad)
air filter (verry old)
inspected and cleaned MAF sensor with MAF sensor cleaner
replaced both corner boots for vacuum line had small cracks (runs from top of engine over to valve cover by cylinder 1)
checked OHMs reading for all four coil packs (reading at .005)
