This happened to my van last year, and at the sugestion of a co-worker, I
disconnected the O2 sensor, and the problem went away. Without cheching
anything else, I ordered one from Vanagain (thank you, sir), problem solved.
I believe you can check the voltage variations of the sensor with a
multimeter, but I'm not sure. After that, the ECU failed, second time in ten
years I've had the van; sent the old one, the one that failed and another
one I bought used to have them repaired locally, no good. I believe I have
the sixth one, and that's the one working. But that's my Ursula, the b..ch,
that's why I don't carry a gas container and matches... Good luck to you.

First, by reflection, which is noblest;
Second, by imitation, which is easiest;
and third by experience, which is the bitterest.
