How old are your O2 Sensors? Do you have generic ones spliced in?

The generic sensors take longer to heat up then OEM ones, thus it may
bog at first.

Subject: [V6-12v] Hesitation at first start


Sometimes my 1994 90S shows an interesting type of hesitation. It
every now and then. I start the car, and start driving. On the very
acceleration (away from the curb) the engine hesitates for a second or
After that it's fine. It only happens on that very first start and
that's it.

The cats are pretty old and I'm suspecting that they might have started
plug up. Does this diagnosis match the symptom described above?
