It's certainly true that a fouled and/or poorly connecte OXS sensor will cause a variety of problems. ??I disconnected and re-connected mine once and immediately could not smoothly rev the engine (it stumbled badly under load in the vicinity of 3000 rpm). ?The problem DID go away with the OXS sensor disconnected, so that's an easy and quick test.

I had a 93 evc and it did the same thing . The dealer couldn't fix it as he
said he had to see it happen . I gave it to them for a week and still no help
as i drove it away from the shop it happened again ,I was so disgusted I
started looking myself even tho it may have voided the warranty.I think the
problem left after i replaced the o2 sensor.I learned to turn the switch off
and on while running down the road ?after awhile it would clear up.There was
bulletine issued by vw that said it could be the contact on the ayr folw
meter that was momentarily losing comtact.
