My car just started doing this the other day.
My car has to crank a bunch of times to fire. 02 won't oscillate at idle, seems to be stuck around 90 volts. Wideband is reading rich at idle. Idle is higher than where it is set. Car backfires a lot on decel. When I let of the throttle the wideband reads rich for a couple of seconds after I let off the throttle instead of reading lean as soon as a let off. And my fuel pressure bleeds off a instantly when normally it will hold pressure for a while.
But the car seems to accelerate fine and cruse fine.
I swapped in another used 02 sensor to see if it changed anything but it didn't. But that 02 could of just as easily been bad too.
Should DSMLink throw a code if the 02 is bad?
