Tony D Posted November 4, 2006 Share Posted November 4, 2006 Unplugged it as in "introduced a massive vacuum leak to lean out the engine"? Methinks a bit more dillegence is in order, there is nothing to go bad in the thing internally, it's activated carbon that stores vapors from the tank. If you are driving to the emissions station, the thing it totally purged and inactive during the testing. Now, if your fuel curve is calibrated wrong and you are running high HC and CO (running rich) disconnecting one of the vacuum lines to the intake manifold will do what was mentioned above and lean it out. Better to check some more. The only thing that goes wrong on them is the check valve on top goes bad (rubber flapper disc) and it leans the engine out. Doesn't sound like that is the case in your situation, matter of fact sounds like the flapper is working just fine sealing it off. It's like cutting your foot off because you tripped on a stick in the road. It was the stick, not the foot causing the problem. Quote Link to comment Share on other sites More sharing options...
