Sick Sable

I retired from this business in 86 about when they started going nuts
with emission requirements. After dealing with these shops I figured
I'll take a stab at it myself so I bought an OBDII scanner and am
learning to use the data supplied by the onboard computer.


I've been fighting this problem for a month. The car has been to the
shop 3 times and still has problems with dying at stop signs,
hesitation, and what feels like a miss at any speed hot or cold, and
sometimes shudders when coming to a stop. It backfires thorugh the intake mainly when cold and stumbles when hot. The car 96 sable 3.0 single
overhead cam with 61000 miles. The parts I have replaced are as
follows:

ect sensor
plugs
wires
maf
tps
egr
pcv
fuel pressure ok
vacuum ok
one upstream o2 sensor (bank 2) today which is operating in specs now.
According to the scanner the o2 voltage on the sensors are almost
running together indicating a bad cat on the #2 bank and the #1 is
starting to look bad. Lately it put out the old rotten egg smell which
usually indicates rich fuel. The #2 bank was rich and the new sensor
took care of that. Since both cats are looking bad I can't hardly
belive the fuel injectors are at fault. I did a back pressure test and it's only 1/2 psi. I haven't been using oil or
water which would foul the cats. I unplugged the cam sensor and no change. It starts up no problem kind of eliminates the crank sensor. I can't put on new cats until I find the cause of the rich fuel mixture. Any ideas would be appreciated. Thanks
