 I have said it before and some disagree But
diconeecting the 02 sensor is not a bad thing especialy if the exhaust is
fouled from other conditions
I know that if you plug a new sensor in when you have driven it full rich
for a day or two only fouls the new sensor. The exhaust sysytem is so sooted
continues to foul the sensor even if the orignial problem is fixed

my list of things to check are
throttle switch
coolant sensor
ground wires at the left head
 and a good old fashoned pin test realy helps

change the oil right away if the gas mileage has dropped to the low teens
