<html><div style='background-color:'><DIV class=RTE>these pesky lil' things!</DIV>
<DIV class=RTE>Okay on my 90 gl i was screwing around with the O2 sensor wire, don't ask why.&nbsp; anyways now with the O2 connected the vans runs supper rich with black smoke and finally sputters then dies.&nbsp; i disconnect the O2 runs great, bit of a high idle though around 1000, but otherwise fine.&nbsp; reconnect the wires, runs bad again.&nbsp; seems to me like a ground thing.&nbsp; if i disconnect the green wire but not the snap wire, it runs fine.&nbsp; if i disconnect the snap wire but connect green wire, it runs bad again.&nbsp; what is up?&nbsp; where does the ground for the O2 go so i can clean it up.&nbsp; why does it run fine without O2, and can i just run it without O2 connected?&nbsp; what does this thing really do except cause problems?</DIV>
<DIV class=RTE>TIA</DIV>

<DIV class=RTE>incidentally this same thing happens on my 87 syncro and that has a new O2, so something else must be going on here!</DIV></div><br clear=all><hr> <a href="http://g.msn.com/8HMBENUS/2755??PS=">Get a FREE online virus check for your PC here, from McAfee.</a> </html>
