Subi81 Posted December 23, 2004 Share Posted December 23, 2004 Was way over on my CO2 at crusing speed. Anyone have any ideas. I passed the idle test with flying colors. I am going to start at the o2 sensor and plugs just did the cap and rotor. Everything else passed, egr, pvc, vaccume hoses. Oh this is on the 86 turbo wagon minus intercooler.

Subi81 Posted December 23, 2004 Author Share Posted December 23, 2004 Heres the printout hope this helps. I am just looking at a jumping piont if anyone sees anything really obvious. Thanks Quote Link to comment Share on other sites More sharing options...
Vanislru Posted December 23, 2004 Share Posted December 23, 2004 My o2 sensor was grounding out right were the wire goes into it, lots of that green electrolysis stuff around it. Car runs much better meow that it's fixed. Quote Link to comment Share on other sites More sharing options...
NorthWet Posted December 23, 2004 Share Posted December 23, 2004 Looks like a problem with HC, not CO2. Tune-up stuff, might consider a new O2 sensor. Just my guess, though. Quote Link to comment Share on other sites More sharing options...
Subi81 Posted December 24, 2004 Author Share Posted December 24, 2004 Yea I figgured it out. Did a full tune up o2 sensor sparkplugs. Did a comp test while I was at it. 120 130 every cylinder. Ok Okk I am getting there. Used my brothers handy dandy vaccum tester and found out that my VACCUME ADVANCE was crap wouldn't hold a vaccum at all. Does this sould like it would lead to a failed cruise emmision test? Thanks Now I just need to get one from somewhere. Quote Link to comment Share on other sites More sharing options...

edrach Posted December 24, 2004 Share Posted December 24, 2004 It shouldn't be too hard to replace the vac advance unit. I know they're still available for around $25 after market for the Hitachi carb. Quote Link to comment Share on other sites More sharing options...
