Having problems with your 2006 Kia Sportage ?
Intermittent Evap Leak
\015 Check engine light comes on after I fill the tank and drive until it hits the 3/4 mark on my gas gauge. It stays on from the 3/4 mark to the 1/2 tank mark then the check engine light goes out. It has done this consistently for about 3 weeks. The diagnostic says it is an intermittent evap leak, the shop did a smoke test but found no leak. Have checked gas cap, no cracks in the seal.\015
Weak power /or poor ground to evap control relay (wiring) common.. also if purge valve stuck open it will not leak externally but let fuel vapors pass back and forth flagging codes..(which it won't due when tank is more full and vapors travel only one direction as designed) good luck
