Hey,

I just installed a one wire type on mine that I got from Napa.  My vanagon is a 83.5, 84 model year.
I don't think you should ground it.  I ran my beast for a couple a years without it.  Not on purpose.
I think you could expect less performance, fuel economy and the works.  It should run however.

Hi everyone:
I am putting my 85 GL back together, and can get it running this
weekend, *IF* I leave off the o2 sensor (can't get it unstuck from old
exhaust system...).

What can I expect from my engine if it is run without the o2 sensor?
Will it run satisifactorily?
Should I do anything with the lead (IE ground it or...??)

Which replacemnt to buy, the 1 wire type or the factory type?

Thanks and Regards,

Rio
